Potentiometer

A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. In motion control systems, potentiometers are frequently used as position sensors to provide analog feedback to a controller, allowing for precise tracking of mechanical movement. If only two terminals are used, one end and the wiper…
