Audio control: Both linear, and rotary potentiometers, are used to control audio equipment for changing the loudness and other audio related signals. Television: They are used to control the picture brightness, colour response and contrast.
What is the need for phase shifters in a polar type AC potentiometers?
To produce the rotating magnetic field which passes through the air gap between its stator and rotor and induces an emf in the rotor winding. To provide the required phase shifting of the rotor induced emf by adjusting the rotor position.
