Debonpotentiometers are rarely used to directly control significant power (more thana watt), since the power dissipated in the potentiometer would be comparable tothe power in the controlled load (see infinite switch). Instead they are usedto adjust the level of analog signals (e.g. volume controls on audio), and ascontrol inputs for electronic circuits. For example, a light dimmer uses apotentiometer to control the switching of a TRIAC and so indirectly control thebrightness of lamps.A potentiometer informally, a pot, is a three-terminalresistor with a sliding contact that forms an adjustable voltage divider. Ifonly two terminals are used (one side and the wiper), it acts as a variableresistor or rheostat. Potentiometers are commonly used to control electricaldevices such as volume controls on audio equipment. Potentiometers operated bya mechanism can be used as position transducers, for example, in a joystick.
