A potentiometer, informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

You mean potentiometer?
It is a device used for measuring electric potential (voltage).
It is used as volume controls on audio equipment and as control inputs for electronic circuits. They are also used as position sensors.
