To put it simply, a potentiometer is a type of resistor that can be manually controlled to change its value of resistance. Thus, increasing or decreasing the output. A potentiometer generally works by adjusting the value of voltage with the help of (you guessed it) potentiometer knobs.

Audio Equipment

Whenever we think about the usage of a potentiometer knob, immediately a volume dial pops up in the head that we can manually turn to control the volume on a stereo or a deck. You might have observed these in your car. Besides volume control, potentiometer knobs are also used to adjust the frequency (for tuning radio channels), control bass and treble, and other audio characteristics.


Potentiometers were widely used in old television sets to control picture brightness, contrast, and color response. These were also used for frequency modulation to catch signals from a satellite.

Light Dimmers

Potentiometers are also used to control lighting situations, especially at studios where different levels of lighting are required to get the best possible shoots.
