Potentiometers

Potentiometers are adjustable resistive components used to control and fine-tune electrical parameters such as voltage, current, signal level, and gain within an electronic circuit. They typically consist of a resistive element and a movable wiper, allowing the resistance or output voltage to be adjusted manually or mechanically across a defined range.

Available in various resistance values, power ratings, tapers, shaft styles, mounting configurations, and package sizes, potentiometers can be selected for precise control or general adjustment applications. They are commonly used for volume controls, display brightness, motor speed adjustment, calibration, user-interface controls, instrumentation, audio equipment, power supplies, and other electronic devices requiring variable electrical adjustment.
