Applications of potentiometers

Potentiometers are used to control volume in audio equipments, frequency attenuation, changing loudness, and changing other characteristics of audio signals. Increasing or decreasing the resistance of the dual rotary potentiometer controls the flow of electric current. If we increase the resistance of the potentiometer, large amount of electric current is blocked and only a small amount of electric current is allowed. On the other hand, if we reduce the resistance of the potentiometer, a large amount of electric current is allowed and only a small amount of electric current is blocked. Huiren Electronics types of Potentiometers are used in televisions and computers to control the picture contrast and brightness.
