2K Potentiometer B2K - 20 mm

The voltage potentiometer, often abbreviated as "pot", is a variable resistor equipped with a sliding or rotary contact that forms an adjustable voltage divider. It typically consists of a resistive element and a sliding contact (wiper) that moves along the resistive element. By changing the position of the wiper, the resistance between the wiper and one or both ends of the resistive element can be adjusted, which changes the output voltage or current.

Varieties of Voltage Potentiometers

Voltage potentiometers are available in various forms, including circular and linear. Rotary voltage potentiometers are usually used in applications that require continuous rotation to change the resistance value, such as volume control tools in audio devices or tuning knobs in radios. Linear voltage potentiometers, on the other hand, are often used in applications that require resistance adjustment along a straight path, such as sliders in mixing control units or in position sensors.

Applications of Voltage Potentiometers

Voltage potentiometers are widely used in electronics and electrical circuits for various purposes, including:
 

• Sound level control in audio equipment: Voltage potentiometers are typically used to adjust the sound level of speakers or headphones.
• Brightness control in displays: Voltage potentiometers can be used to adjust the brightness of displays such as LCD screens or LED panels.
• Motor speed control: Voltage potentiometers are used in motor control circuits to change the speed of DC motors.
• Frequency tuning and adjustment: In radios and other communication devices, voltage potentiometers are used to tune different frequencies or adjust the frequency of oscillators.
• Sensing and measurement: Voltage potentiometers can be used as sensors to measure the position or angle or displacement of mechanical components.

In general, voltage potentiometers are versatile components that find applications in a wide range of electronic devices and systems.
