Potentiometer: Learn about potentiometers

Learn about potentiometers, variable resistors with a sliding contact that can be adjusted to change the resistance. See different types, symbols, constructions, applications and wiring diagrams of POTs. Key learnings: Potentiometer Definition: A potentiometer (also known as a pot or potmeter) is defined as a 3-terminal variable resistor used to control the flow of electric current by adjusting resistance. Working Principle: Potentiometers work by moving a sliding contact across a uniform resistance, adjusting the voltage output based on the contact’s position. Types of Potentiometers: There are two main types of potentiometers: rotary, which adjusts by rotating, and linear, which adjusts ... A potentiometer , also known as a variable resistor, is a three-terminal electronic device used to measure the electromotive force (EMF) of a cell and its internal resistance. It finds applications in various electronics equipment, allowing users to modify electrical circuits for desired outputs. In radios, potentiometers are commonly used for volume control and in other audio electronic equipment.
