MT10 1M ohm 1/4w 5% Multi Turn Potentiometer (105) 3296W
The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage).
Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load.
