Potentiometer, puh tehn shee OM uh tuhr, is a device that measures electric current, voltage, and resistance with high precision. It shows voltage differences by comparing an unknown electromotive force with a known one. It is used to calibrate voltmeters or ammeters, and as a control element in electronic circuits and devices.
