WebA potentiometer is also commonly referred to as a pot. These potentiometers have three terminal connections. One terminal is connected to a sliding contact called a wiper, and the other two terminals are connected to fixed resistance tracks. wipers can be moved along the resistive track using either linear sliding controls or a rotary “wiper” contact. Potentiometers are rarely used to directly control significant amounts of power (more than a watt or so). Instead they are used to adjust the level of analog signals (for example volume controls audio equipment), and as control inputs for electronic circuits. For example, a light dimmer uses a potentiometer to control the switching of a TRIAC and so indirectly to control the brightness of lamps.
