Potentiometer: Your All-in-One Learning Portal

Your All-in-One Learning Portal: GeeksforGeeks is a comprehensive educational platform that empowers learners across domains-spanning computer science and programming, school education, upskilling, commerce, software tools, competitive exams, and more. Learn about potentiometers, variable resistors that control and measure electrical signals. Compare them with rheostats and encoders, and explore their construction, specifications, and design considerations. Potentiometer – Working, Circuit Diagram, Construction & Types Resistor, a small bundle of resistance, is one of the most used basic components in an electric circuit. Mostly used to regulate the current flow by adding/subtracting resistance from the circuit, these resistors are available in many shapes and sizes. These resistors can be broadly classified as fixed and variable resistors. As their respective names suggest, a fixed resistor has a single fixed value of resistance, whereas a ... What is a potentiometer ? The potentiometer is a 3-terminal resistor that comes with a sliding or rotating contact that makes an adjustable voltage divider. If two terminals use one end and wiper it works as a variable resistor or rheostat. The measuring instruments are known as voltage dividers used for measuring electrical potential; the component is the implementation of the same working. A potentiometer is used to control electrical devices like volume controls on audio instruments. It is ...
