Potentiometers, Variable Resistors

Potentiometers and variable resistors are electronic components used to regulate the flow of electrical current in a circuit. They consist of a resistor that can change its resistance in response to an external input, allowing for precise control over voltage levels or current flow. These components are commonly used in audio equipment, motor controls, and other applications where precise adjustment of power is required. They come in various forms such as rotary potentiometers with a dial or slide, and linear potentiometers with a sliding element.
