potentiometer
Also known as trimpot, trimmer pot, thumb pot, thumbwheel pot, slide pot, slider pot, pot
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, it acts as a variable resistor or rheostat.

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, it acts as a variable resistor or rheostat.
The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.
