Potentiometers

Potentiometers are variable resistors used to control electrical resistance in circuits. Consisting of a resistive element and a movable contact, they allow manual adjustment of voltage or current. The resistor's entire length determines the maximum resistance, while the movable contact regulates the output. Commonly used in volume controls and tuning applications, potentiometers provide a smooth, continuous change in resistance, enabling precise adjustments. Their diverse forms, including rotary and linear types, cater to various electronic applications, offering a versatile solution for tuning and calibration in electronic devices.
