A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. It is used to control the electrical resistance of a circuit, thereby controlling the flow of current. Potentiometers are commonly used in audio and electronic circuits to control volume, gain, and other parameters.
The importance of potentiometers lies in their ability to provide precise and variable control over electrical signals. They are widely used in a variety of applications, including:
