A potentiometer is a three-terminal resistor that allows for variable resistance. Typically used for adjusting levels, such as volume or brightness, its operation is based on a sliding or rotating contact (wiper) that moves along a resistive element. This versatility makes potentiometers integral to countless electronic applications.

How Potentiometers Work

The primary function of a potentiometer is to adjust voltage and current within a circuit. By altering the resistance, the wiper modifies the amount of electrical signal passing through, thus controlling the output. For instance, in audio applications, turning a potentiometer adjusts the volume by controlling the signal level sent to the amplifier.

What is a 22k Potentiometer?

A 22k potentiometer specifically has a resistance value of 22,000 ohms. It can be found in various forms, including linear and logarithmic types, catering to different applications. The choice of a 22k potentiometer often stems from its compatibility with various circuits, making it a popular choice among engineers and hobbyists alike.
