<h1><span style="font-weight: 400; color: #000080;">Introduction to Electronic Circuits: Active vs. Passive Components</span></h1>
<p>Active and passive electronic components distinguish between themselves,while circuits are determined by their active and passive components. <span style="font-weight: 400;">Learning to identify active and passive components and how these components are connected to the circuits is important for circuitous use.</span></p>
<h1><span style="color: #000080;"><span style="font-weight: 400;">Electronic Circuits: Active vs. Passive Components </span><span style="font-weight: 400;">Article</span></span></h1>
<p><span style="font-weight: 400;">In electronic circuits,there are two main types of components: active and passive. Active components,such as transistors and integrated circuits,require a power supply to operate,while passive components,such as resistors and capacitors,do not. Active components can amplify or switch electrical signals,while passive components can only filter or delay them.</span></p>
<p><span style="font-weight: 400;">According to electronic engineers,the terms "active" and "passive" are used to define the parts and circuits of a device or circuit that are directly responsible for increasing a signal. In this article,we will be exploring active versus passive components and their precise roles in circuits.</span></p>
<p> </p>
<p>The purpose of this article is to provide an introduction to electronic circuits,specifically active and passive components. Passive components are the simplest type of component and are made from materials that do not require electrical power to operate,such as resistors and capacitors. Active components,such as transistors and integrated circuits,require electrical power to operate.</p>
<p>In this article we will learn about the components and operation of transistors,diodes,integrated circuits and the basic electrical circuit. We will also learn how to use resistors and capacitors in circuits.</p>
<h4><strong>What is a transistor?</strong></h4>
<p>A <strong><span style="color: #333399;">transistor</span></strong> is a semiconductor device that can act as an amplifier,a switch and even as a light source. They are widely used in all kinds of electronic circuits such as amplifiers,radios,TVs and computers.</p>
<h2><span style="color: #333399;">Active Components and Passive components</span></h2>
<p>An active component is an electronic device that requires power to operate. An active component may consist of a small number of transistors,integrated circuits and other components. Active components include amplifiers,oscillators and the like. A passive component does not require power to operate.</p>
<h2><span style="color: #333399;"><strong>Active Components</strong></span></h2>
<p><span style="font-weight: 400;">The active components of an electronic circuit are the devices that provide the power and control signals to the circuit. The three most common active components are transistors,integrated circuits,and diodes. Each type of component has unique properties that make it suitable for a particular application.</span></p>
<p><span style="color: #333399;"><i><span style="font-weight: 400;">Examples of active components; a microcontroller,a power MOSFET,and an IC</span></i></span></p>
<h2><span style="color: #333399;"><strong>Passive Components</strong></span></h2>
<p><i><span style="font-weight: 400;">Passive components are essential for creating circuits with specific functions. The most common type of passive component is the resistor,which is used to control the flow of electricity through a circuit.</span></i></p>
<p><i><span style="font-weight: 400;">Passive components are relatively easy to manufacture and include resistors,inductors,and capacitors.</span></i></p>
<p><i><span style="font-weight: 400;">Passive components will always experience loss. Inherent losses indicate a decrease in power between the input and output signals,as well as a decrease in amplification.</span></i></p>
<p><i><span style="font-weight: 400;">For instance,a transformer can boost the voltage of an electric signal during step-up configurations. As a result,the transformer's output power will be equal to or less than that of its input,and the transformer is only useful for power factor correction.</span></i></p>
<p><i><span style="font-weight: 400;">Examples of passive components; a crystal,various capacitors and resistors,and other resistors</span></i></p>
<h3><b><i>Determining Electronic circuit active and inactive components</i></b></h3>
[caption id="attachment_4407" align="alignnone" width="750"]<img class="wp-image-4407 size-full" src="https://teachmeanything.net/blogeduengwork/wp-content/uploads/2022/03/electronic-circuit-1.png" alt="electronic circuit active passive components" width="750" height="422" />  [/caption]
<p><span style="font-weight: 400;">It can be difficult to determine whether a component is active or passive. For example,diodes are often misidentified as active parts,but they are actually passive. Whether a component can control a current using another often determines whether its behavior is passive or active.</span></p>
<p><span style="font-weight: 400;">Another option is to identify a particular element that is involved. For instance,in the case of a tunnel diode,it is designed for quick operation. Its normal operating range exhibits zero resistance while increasing the input power reduces the electric current contained — which makes it an oscillator. This function makes it an active component.</span></p>
<p>This is a very useful tool for determining what electronic components are in a circuit and whether or not they are active</p>
<p><span style="font-weight: 400;">A part users often take into consideration is a relay. A relay includes a switch triggered by a coil and can be used for switching high power sources with an intake of low power. Relays are digital and could be considered an oscillator,but they can be utilized to make logical gates and even computers,making them passive.</span></p>

<h1 style="text-align: center;"><span data-preserver-spaces="true">Create Your Very Own Portable Power Supply for Your Microcontroller Projects</span></h1>
<h2 style="text-align: center;"><em><span data-preserver-spaces="true">Level of Difficulty: </span></em><span data-preserver-spaces="true">Intermediate</span></h2>
&nbsp;

<img class=" wp-image-3864 aligncenter" src="https://eduengteam.com/wp-content/uploads/2021/08/Fascinating-Portable-Power-Supply-For-Your-Microcontroller-Projects-300x202.jpg" alt="Fascinating Portable Power Supply" width="602" height="406" />

&nbsp;
<h3><strong><span data-preserver-spaces="true">Why do we need to build this project?</span></strong></h3>
<span data-preserver-spaces="true">Most of the time,we use <a href="https://www.techopedia.com/definition/8093/lithium-polymer-battery-lipo-battery">Lithium-ion or Li-Po batteries</a> to power our projects,especially when working with microcontroller projects in remote places. Since Li-Po batteries are rechargeable batteries with a small size,it makes them convenient to use. </span>

&nbsp;

<span data-preserver-spaces="true">However,the most common issue we have with these batteries is their volts. It only ranges from 3.7 volts to a maximum of 4.2 volts. </span><span data-preserver-spaces="true">Mostly,the common volt for microcontrollers and sensors to work is either 3.3 volts or 5 volts.</span>

&nbsp;

<span data-preserver-spaces="true">Thus,we must have a buck or boost converter and a charging circuit. With this,we can adjust the voltage to the required voltage.</span>

&nbsp;

<span data-preserver-spaces="true">You might be wondering,why can't we simply use a power bank then? Yes,it is portable and can hold 5 volts; however,it also has limitations. </span>

&nbsp;

<span data-preserver-spaces="true">Normally,it needs to have at least 80 mA to keep the device turned on. Once you use deep sleep to save power,using the power bank would be ineffective and pointless. </span>

&nbsp;

<span data-preserver-spaces="true">Hence,we are building this project to have an adequate,and reliable power supply that would our work as smooth as butter.</span>

&nbsp;

&nbsp;
<h3><span data-preserver-spaces="true">List of the things needed for this project:</span></h3>
<ul>
 	<li><span data-preserver-spaces="true">One (1) Soldering iron</span></li>
 	<li><span data-preserver-spaces="true">One (1) TP4056 1A Standalone Linear Li-lon Battery Charger </span></li>
 	<li><span data-preserver-spaces="true">Two (2) MT3608 Boost Converter</span></li>
 	<li><span data-preserver-spaces="true">One (1) Battery Holder with 2 slots for a 18650 Rechargeable Li-ion Battery</span></li>
</ul>
&nbsp;

<span data-preserver-spaces="true">Once all the materials are prepared,then we are ready to start building this project!</span>

&nbsp;

&nbsp;
<h3><span data-preserver-spaces="true">Let's Take a Closer Look At Our Materials</span></h3>
&nbsp;

<img class="alignnone wp-image-3867 aligncenter" src="https://eduengteam.com/wp-content/uploads/2021/08/USB-type-C-and-micro-USB-port-300x221.jpg" alt="Portable Power Supply" width="607" height="447" />

&nbsp;

<span data-preserver-spaces="true">There are two USB ports: USC Type-C and Micro USB. These are for charging and it can run two 18650 li-ion batteries; thus,having a 500 mAh backup for the battery.</span>

&nbsp;

<img class=" wp-image-3868 aligncenter" src="https://eduengteam.com/wp-content/uploads/2021/08/Circuit-for-Portable-Power-Supply-300x300.jpg" alt="Portable Power Supply" width="513" height="514" />

&nbsp;

<span data-preserver-spaces="true">Then,we have three separate outputs: 3.3 volts,5.5 volts,and an adjustable voltage that meets the required power.</span>

&nbsp;

<img class="wp-image-3870 aligncenter" src="https://eduengteam.com/wp-content/uploads/2021/08/Schematic-1-300x290.jpg" alt="Portable Power Supply Schematic" width="560" height="541" />

&nbsp;

<span data-preserver-spaces="true">For our schematic,we have a TP4056 battery charging IC. TP4056,with the DW01A and FS8205A,produces a variety of features to protect our battery from short circuits,reverse polarity,and even over-charging or over-discharging.</span>

&nbsp;

<span data-preserver-spaces="true">We also have two MT3608 boost converter circuits for 5v and adjustable voltage output,and an AMS1117 LDO to have the 3.3v output.</span>

&nbsp;

<span data-preserver-spaces="true">Now that our materials are all set,we are ready to begin.</span>

&nbsp;

&nbsp;
<h3><span data-preserver-spaces="true">Let's Get Started</span></h3>
&nbsp;

Now,I will teach you a to create your very own Portable Power Supply that is perfect for working in distant places. The following consists of step-by-step instructions that you can easily follow.

&nbsp;

<img class=" wp-image-3871 aligncenter" src="https://eduengteam.com/wp-content/uploads/2021/08/Board-for-Portable-Power-Supply-300x196.jpg" alt="Board for Portable Power Supply" width="520" height="339" />

&nbsp;

<span data-preserver-spaces="true">First,insert the batteries in the board to charge it and that may take approximately 2.5 hours to charge it fully. </span><span data-preserver-spaces="true">Subsequently,check the current consumption on standby. It may take 1.8 mA and may get lower when you withdraw the light indicator. </span>

&nbsp;

<span data-preserver-spaces="true">Afterward,you may turn on or off each output using the respective switches. Here,you will notice that the LED indicates which one is turned on and turned off. </span>

&nbsp;

<img class=" wp-image-3872 aligncenter" src="https://eduengteam.com/wp-content/uploads/2021/08/Boost-Convert-Circuit-for-Portable-Power-Supply-300x221.jpg" alt="Boost Converter Circuit for Portable Power Supply" width="627" height="463" />

&nbsp;

<span data-preserver-spaces="true">Now,we have a reliable 5 volts from the first boost converter circuit. On the adjustable part,we can modify it to a maximum of 13 volts with the use of 470 ohms and a 10k pot. You can also adjust it up to 28 volts if you use a 2k2 resistor and 100k pot.</span>

&nbsp;

<span data-preserver-spaces="true">Then,add a small voltmeter so that we can see the adjustable voltage readings. We may get the output from DC barrel jacks,screw terminals,or the header pins and for 5-volt output. </span>

&nbsp;

<span data-preserver-spaces="true">For us to plug any USB device directly,we will have a female USB connector. Moreover,we can include JST connectors to connect and charge some external batteries.</span>

&nbsp;

<img class=" wp-image-3873 aligncenter" src="https://eduengteam.com/wp-content/uploads/2021/08/Battery-Status-for-Portable-Power-Supply-300x158.jpg" alt="Battery Status for Portable Power Supply" width="612" height="323" />

&nbsp;

<span data-preserver-spaces="true">Finally,measuring the charging status. It is very convenient when working with microcontrollers. </span>With this,we connect some header pins to the analog pins of the microcontrollers and get the charging status.

&nbsp;

Now,with your new Portable Power Supply,you can freely do your microcontroller projects anywhere you want without any hassle.

[1] </span><span style="vertical-align: inherit;">إذا تم استخدام طرفين فقط ، طرف واحد والمساحة ، فإنها تعمل كمقاوم متغير أو مقاومة متغيرة</span></span>

<img class="wp-image-3313 aligncenter" src="https://www.eduengteam.com/wp-content/uploads/2020/12/800px-Electronic-Component-hالجهد-297x300.jpg" alt="" width="176" height="178" />

<span style="vertical-align: inherit;"><span style="vertical-align: inherit;">إن أداة القياس التي تسمى </span></span><a href="https://www.eduengteam.com/?p=3312&amp;preview=true"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">مقياس الجهد</span></span></a><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"> هي في الأساس مقسم جهد يستخدم لقياس الجهد الكهربائي (الجهد) ؛ </span><span style="vertical-align: inherit;">المكون هو تنفيذ لنفس المبدأ ، ومن هنا جاء اسمه.</span></span>
<h2><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">التسمية</span></span></h2>
<span style="vertical-align: inherit;"><span style="vertical-align: inherit;">هناك عدد من المصطلحات في صناعة الإلكترونيات تستخدم لوصف أنواع معينة من مقاييس فرق الجهد:</span></span>
<ul>
 	<li><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">وعاء منزلق أو وعاء منزلق: مقياس جهد يتم ضبطه عن طريق تحريك الماسحة إلى اليسار أو اليمين (أو لأعلى ولأسفل ، اعتمادًا على التركيب) ، عادةً بإصبع أو إبهام</span></span></li>
 	<li><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">وعاء الإبهام أو وعاء الإبهام: مقياس جهد دوار صغير يُقصد به تعديله بشكل غير متكرر باستخدام عجلة صغيرة</span></span></li>
 	<li><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">أداة التشذيب أو وعاء التشذيب: مقياس جهد أداة التشذيب يُقصد به تعديله مرة واحدة أو نادرًا من أجل "ضبط" إشارة كهربائي</span></span></li>
</ul>
&nbsp;
<h3><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">اعمال بناء</span></span></strong></h3>
<span style="vertical-align: inherit;"><span style="vertical-align: inherit;">تتكون مقاييس الجهد من عنصر مقاوم ، وملامس منزلق (ممسحة) يتحرك على طول العنصر ، مما يجعل اتصالًا كهربائيًا جيدًا مع جزء منه ، ومحطات كهربائية في كل طرف من نهاية العنصر ، وهي آلية تنقل الماسحة من طرف إلى آخر ، ومبيت يحتوي على عنصر ومساحة.</span></span>

<span style="vertical-align: inherit;"><span style="vertical-align: inherit;">يتم إنشاء </span><span style="vertical-align: inherit;">العديد من </span></span><a href="https://www.eduengteam.com/?p=3312&amp;preview=true"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">مقاييس الجهد</span></span></a><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"> غير المكلفة </span><span style="vertical-align: inherit;">باستخدام عنصر مقاوم (B في الرسم المقطوع) يتكون في قوس من دائرة عادة ما يكون أقل بقليل من دورة كاملة وممسحة (C) تنزلق على هذا العنصر عند تدويرها ، مما يؤدي إلى اتصال كهربائي. </span><span style="vertical-align: inherit;">يمكن أن يكون عنصر المقاومة مسطحًا أو مائلًا. </span><span style="vertical-align: inherit;">كل طرف من عناصر المقاومة متصل بطرف (E ، G) في العلبة. </span><span style="vertical-align: inherit;">يتم توصيل الماسحة بطرف ثالث (F) ، عادة بين الطرفين الآخرين. </span></span>

<img class="wp-image-3314 aligncenter" src="https://www.eduengteam.com/wp-content/uploads/2020/12/بناء-الجهد.png" alt="" width="157" height="130" />

<span style="vertical-align: inherit;"><span style="vertical-align: inherit;">نوع آخر هو مقياس الجهد المنزلق الخطي ، والذي يحتوي على ممسحة تنزلق على طول عنصر خطي بدلاً من الدوران. </span><span style="vertical-align: inherit;">يمكن أن يدخل التلوث في أي مكان على طول الفتحة التي يتحرك فيها شريط التمرير ، مما يجعل الختم الفعال أكثر صعوبة ويهدد الموثوقية طويلة المدى. </span><span style="vertical-align: inherit;">من مزايا مقياس الجهد المنزلق أن موضع شريط التمرير يعطي إشارة مرئية لإعداده. </span><span style="vertical-align: inherit;">بينما يمكن رؤية إعداد مقياس الجهد الدوراني من خلال موضع علامة على المقبض ، يمكن لمجموعة من المنزلقات أن تعطي انطباعًا مرئيًا عن الإعدادات كما هو الحال في المعادل الرسومي أو الخافتات على وحدة المزج.</span></span>

<span style="vertical-align: inherit;"><span style="vertical-align: inherit;">غالبًا ما يتكون عنصر المقاومة لمقاييس الجهد الرخيصة من الجرافيت. </span><span style="vertical-align: inherit;">تشمل المواد الأخرى المستخدمة سلك المقاومة وجزيئات الكربون في البلاستيك وخليط من السيراميك / المعدن يسمى سيرميت. </span><span style="vertical-align: inherit;">تستخدم مقاييس الجهد الموصلة للمسار معاجين موصلة لمقاومة البوليمر التي تحتوي على راتنجات وبوليمرات ومذيبات ومواد تشحيم شديدة التحمل ، بالإضافة إلى الكربون الذي يوفر الخصائص الموصلة </span></span><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">.</span></span></strong>

<span class="tw-flex-1 tw-pr-4 tw-truncate"><span class=""><a class="router-link-active" title="عرض نتائج &quot;كيفية توصيل مقياس جهد&quot;" href="https://www.spyfu.com/keyword/overview?query=how%20to%20wire%20a%20potentiometer"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">كيفية توصيل مقياس الجهد</span></span></a></span></span>
<p style="background: white;"><span style="font-size: 10.5pt; font-family: 'Arial','sans-serif'; color: #202122;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">يمكن تزويد مقاييس فرق الجهد الدوارة التي يمكن للمستخدم الوصول إليها بمفتاح يعمل عادةً في أقصى عكس اتجاه عقارب الساعة للدوران. </span><span style="vertical-align: inherit;">قبل أن تصبح الإلكترونيات الرقمية هي القاعدة ، تم استخدام مثل هذا المكون للسماح بتشغيل أجهزة استقبال الراديو والتلفزيون وغيرها من المعدات بأدنى مستوى صوت بنقرة مسموعة ، ثم زاد الحجم عن طريق تدوير المقبض. </span><span style="vertical-align: inherit;">يمكن تجميع عناصر مقاومة متعددة مع جهات الاتصال المنزلقة الخاصة بهم على نفس العمود ، على سبيل المثال ، في مكبرات صوت ستيريو للتحكم في مستوى الصوت. </span><span style="vertical-align: inherit;">في التطبيقات الأخرى ، مثل مخفتات الإضاءة المحلية ، يكون نمط الاستخدام العادي أكثر إرضاءًا إذا ظل مقياس الجهد مضبوطًا في موضعه الحالي ، لذلك يتم تشغيل المفتاح عن طريق إجراء دفع ، بالتناوب بين التشغيل والإيقاف ، عن طريق الضغط المحوري للمقبض.</span></span></span></p>
<p style="background: white; margin: 6.0pt 0cm 6.0pt 0cm;"><span style="font-size: 10.5pt; font-family: 'Arial','sans-serif'; color: #202122;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">يتم تضمين البعض الآخر داخل الجهاز ويهدف إلى تعديله لمعايرة المعدات أثناء التصنيع أو الإصلاح ، ولم يتم لمسها بأي طريقة أخرى. </span><span style="vertical-align: inherit;">عادة ما تكون أصغر بكثير من مقاييس الجهد التي يمكن للمستخدم الوصول إليها ، وقد تحتاج إلى تشغيلها بواسطة مفك براغي بدلاً من وجود مقبض. </span><span style="vertical-align: inherit;">وعادة ما يطلق عليهم "مقاييس فرق الجهد المحددة مسبقًا" أو "تقليم [مينغ] الأواني". </span><span style="vertical-align: inherit;">يمكن الوصول إلى بعض الإعدادات المسبقة بواسطة مفك براغي صغير مثقوب من خلال ثقب في العلبة للسماح بالصيانة دون تفكيك.</span></span></span></p>

<span style="vertical-align: inherit;"><span style="vertical-align: inherit;">الطريقة الأكثر شيوعًا لتغيير المقاومة في الدائرة هي استخدام مقاومة متغيرة. </span><span style="vertical-align: inherit;">صاغ السير تشارلز ويتستون كلمة ريوستات حوالي عام 1845 ، من اليونانية ῥέος rheos التي تعني "تيار" ، و -states (من ἱστάναι هيستاناي ، "للتعيين ، للتسبب في الوقوف") والتي تعني "جهاز التنظيم ، الجهاز المنظم" ، ] [7] [8] وهو مقاوم متغير ذو طرفين. </span><span style="vertical-align: inherit;">أصبح مصطلح "مقاومة متغيرة" قديمًا ، [9] مع المصطلح العام "مقياس الجهد" ليحل محله. </span><span style="vertical-align: inherit;">بالنسبة للتطبيقات منخفضة الطاقة (أقل من حوالي 1 واط) ، غالبًا ما يتم استخدام مقياس جهد ثلاثي الأطراف ، مع طرف واحد غير متصل أو متصل بالممسحة</span></span>

<strong>Today,in this amazing article,we will talk about everything potentiometer</strong>

A potentiometer is  a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.[1] If only two terminals are used,one end and the wiper,it acts as a variable resistor or rheostat

The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle,hence its name.

Potentiometer are  commonly used to control electrical devices such as volume controls on audio equipment. Potentiometer operated by a mechanism can be used as position transducers,for example,in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt),since the power dissipated in the potentiometer would be comparable to the power in the controlled load.
<h2>Nomenclature</h2>
<strong>There are a number of terms in the electronics industry used to describe certain types of <a href="https://www.eduengteam.com/?p=3318&amp;preview=true">potentiometers</a>:</strong>
<ul>
 	<li>slide pot or slider pot: a <a href="https://www.eduengteam.com/?p=3318&amp;preview=true">potentiometer</a> that is adjusted by sliding the wiper left or right (or up and down,depending on the installation),usually with a finger or thumb</li>
 	<li>thumb pot or thumbwheel pot: a small rotating <a href="https://www.eduengteam.com/?p=3318&amp;preview=true">potentiometer</a> meant to be adjusted infrequently by means of a small thumbwheel</li>
 	<li>trimpot or trimmer pot: a trimmer potentiometer typically meant to be adjusted once or infrequently for "fine-tuning" an electrical signal</li>
</ul>
<h2><strong>Construction</strong></h2>
Potentiometers consist of a resistive element,a sliding contact (wiper) that moves along the element,making good electrical contact with one part of it,electrical terminals at each end of the element,a mechanism that moves the wiper from one end to the other,and a housing containing the element and wiper.

Many inexpensive potentiometers are constructed with a resistive element

(B in cutaway drawing) formed into an arc of a circle usually a little less than a full turn and a wiper (C) sliding on this element when rotated,making electrical contact. The resistive element can be flat or angled. Each end of the resistive element is connected to a terminal (E,G) on the case. The wiper is connected to a third terminal (F),usually between the other two. On panel potentiometers,the wiper is usually the center terminal of three. For single-turn potentiometers,this wiper typically travels just under one revolution around the contact. The only point of ingress for contamination is the narrow space between the shaft and the housing it rotates in.

&nbsp;

Another type is the linear slider <a href="http://www.eduengteam.com">potentiometer</a>,which has a wiper which slides along a linear element instead of rotating. Contamination can potentially enter anywhere along the slot the slider moves in,making effective sealing more difficult and compromising long-term reliability.

An advantage of the slider potentiometer is that the slider position gives a visual indication of its setting. While the setting of a rotary <a href="http://www.eduengteam.com">potentiometer</a> can be seen by the position of a marking on the knob,an array of sliders can give a visual impression of settings as in a graphic equalizer or faders on a mixing console.

The resistive element of inexpensive potentiometers is often made of graphite. Other materials used include resistance wire,carbon particles in plastic,and a ceramic/metal mixture called cermet.

Conductive track potentiometers use conductive polymer resistor pastes that contain hard-wearing resins and polymers,solvents,and lubricant,in addition to
<p style="background: white;"><span style="font-size: 10.5pt; font-family: 'Arial','sans-serif'; color: #202122;">.</span> <span style="font-size: 10.5pt; font-family: 'Arial','sans-serif'; color: #202122;">A string potentiometer is a multi-turn potentiometer operated by an attached reel of wire turning against a spring,enabling it to convert linear position to a variable resistance.</span></p>
<p style="background: white;"><span style="font-size: 10.5pt; font-family: 'Arial','sans-serif'; color: #202122;">User-accessible rotary potentiometers can be fitted with a switch which operates usually at the anti-clockwise extreme of rotation. Before digital electronics became the norm such a component was used to allow radio and television receivers and other equipment to be switched on at minimum volume with an audible click,then the volume increased,by turning a knob. Multiple resistance elements can be ganged together with their sliding contacts on the same shaft,for example,in stereo audio amplifiers for volume control. In other applications,such as domestic light dimmers,the normal usage pattern is best satisfied if the potentiometer remains set at its current position,so the switch is operated by a push action,alternately on and off,by axial presses of the knob.</span></p>
<a href="https://www.eduengteam.com/?p=3318&amp;preview=true"><strong>Rheostat</strong></a>

&nbsp;

<img class="alignnone wp-image-3315" src="https://www.eduengteam.com/wp-content/uploads/2020/12/مقاومه-300x181.jpg" alt="" width="210" height="127" />

The most common way to vary the resistance in a circuit is to use a <strong>rheostat</strong>. The word <em>rheostat</em> was coined about 1845 by Sir <a href="http://www.eduengteam.com/">Charles Wheatstone</a>,<em>rheos</em> meaning "stream",and -<em>states</em> ( ι <em>histanai</em>," to set,to cause to stand") meaning "setter,regulating device",which is a two-terminal variable resistor. The term "rheostat" is becoming obsolete with the general term "<a href="https://www.eduengteam.com/?p=3318&amp;preview=true">potentiometer</a>" replacing it. For low-power applications (less than about 1 watt) a three-terminal potentiometer is often used,with one terminal unconnected or connected to the wiper.

<h4><strong>Main article: Digital potentiometer</strong></h4>
Usage of a digipot is far more complex than that of a simple mechanical potentiometer,and there are many limitations to observe; nevertheless they are widely used,often for factory adjustment and calibration of e equipment,especially where the limitations of mechanical potentiometers are problematic.

A digipot is generally immune to the effects of moderate long-term mechanical vibration or environmental contamination,to the same extent as other semiconductor devices,and can be secured electronically against unauthorised tampering by protecting the access to its programming inputs by various means.

&nbsp;

In equipment which has a microprocessor,FPGA or other functional logic which can store settings and reload them to the "<a href="https://www.eduengteam.com/">potentiometer</a>" every time the equipment is powered up,a multiplying DAC can be used in place of a digipot,and this can offer higher setting resolution,less drift with temperature,and more operational flexibilit
<h4>Applications</h4>
Potentiometers are rarely used to directly control significant amounts of power (more than a watt or so). Instead they are used to adjust the level of analog signals (for example <a href="https://en.wikipedia.org/wiki/Loudness">volume</a> controls on <a href="https://en.wikipedia.org/wiki/Audio_equipment">audio equipment</a>),and as control inputs for electronic circuits. For example,a light <a href="https://en.wikipedia.org/wiki/Dimmer">dimmer</a> uses a potentiometer to control the switching of a <a href="https://en.wikipedia.org/wiki/TRIAC">TRIAC</a> and so indirectly to control the brightness of lamps.

Preset potentiometers are widely used throughout electronics wherever adjustments must be made during manufacturing or servicing.

User-actuated potentiometers are widely used as user controls,and may control a very wide variety of equipment functions. The widespread use of potentiometers in consumer electronics declined in the 1990s,with rotary <a href="https://en.wikipedia.org/wiki/Incremental_encoder">incremental encoders</a>,up/down <a href="https://en.wikipedia.org/wiki/Push-button">push-buttons</a>,and other digital controls now more common. However they remain in many applications,such as volume controls and as position sensors.
