Types of Potentiometers

A potentiometer is also commonly known as pot. These potentiometers have three terminal connections. 


One terminal connected to a sliding contact called wiper and the other two terminals are connected to a fixed resistance track. 


The wiper can be moved along the resistive track either by use of a linear sliding control or a rotary “wiper” contact. Both rotary and linear controls have the same basic operation.


The most common form of the potentiometer is the single turn rotary potentiometer. This type of potentiometer is often used in audio volume control (logarithmic taper) as well as many other applications. Different materials are used to construct potentiometers, including carbon composition, cermet, conductive plastic, and the metal film.
