Potentiometers consist of a resistive element, a sliding contact (wiper) that moves along the element, making good electrical contact with one part of it, electrical terminals at each end of the element, a mechanism that moves the wiper from one end to the other, and a housing containing the element and … See more A potentiometer 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. See more The most common way to vary the resistance in a circuit continuously is to use a rheostat. It is basically used to adjust magnitude of current in a circuit by changing length. The word rheostat was coined about 1845 by Sir Charles Wheatstone, … See more A membrane potentiometer uses a conductive membrane that is deformed by a sliding element to contact a resistor voltage divider. … See more • Potentiometric sensor • Trimmer See more Some terms in the electronics industry used to describe certain types of potentiometers are: • Slide pot or slider pot: a potentiometer that is adjusted by sliding the wiper left or right (or up and down, depending on the installation), usually … See more A digital potentiometer (often called digipot) is an electronic component that mimics the functions of analog potentiometers. … See more Potentiometers are rarely used to directly control significant amounts of power (more than a watt or so).
