In this guide, I’ll show you what the potentiometer looks like on the inside, the different potentiometer types, and examples of how to wire it up for different circuits. Potentiometers, often referred to as "pots", are fundamental components in the realm of electrical engineering. These versatile devices play a pivotal role in controlling and measuring electrical signals, providing a dynamic interface between circuits and the physical world they interact with. The potentiometer, commonly referred to as a “pot”, is a three-terminal mechanically operated rotary analogue device which can be found and used in a large variety of electrical and electronic circuits. A potentiometer is an electrical device used to measure and compare voltages accurately without drawing current from the circuit. It consists of a resistive wire and a sliding contact (wiper) that moves along the wire to adjust the voltage. This application note lists a number of application circuits for Intersil’s digitally-controlled (XDCP) potentiometers. The application circuits illustrate the wide variety of possible functions which ... For related background details, please refer to our report on metal conduit for electrical wiring. This is a digitally controllable electronic potentiometer. The heart of the circuit is a 16 channel analog multiplexer. Controlled by the BCD value at the inputs, the output pin of the multiplexer ... Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. It is also used in speed control of fans. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. What is a Potentiometer? A potentiometer (also known as a pot or potmeter) is defined as a 3 terminal variable resistor in which the resistance is manually varied to control the flow of electric current. A potentiometer acts as an adjustable voltage divider.
