potentiometer

A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. It is used to control the electrical current flowing through a circuit. Potentiometers are commonly used in electronic circuits to adjust the volume of audio signals, the brightness of lights, or the speed of motors.

To check a potentiometer, you will need a multimeter. Set the multimeter to the ohms setting. Connect the positive lead of the multimeter to one of the outer terminals of the potentiometer. Connect the negative lead of the multimeter to the other outer terminal of the potentiometer. Adjust the sliding or rotating contact of the potentiometer and observe the reading on the multimeter. The reading should change as you adjust the contact.

A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. It is used to control the electrical resistance of a circuit, and as such, can be used to control the flow of current or voltage. Potentiometers are commonly used in audio applications to control volume, tone, and other parameters.

There are several ways to check a potentiometer. One way is to use a multimeter to measure the resistance between the terminals. Another way is to apply a voltage to the potentiometer and measure the voltage at the wiper terminal. If the potentiometer is working properly, the voltage at the wiper terminal will vary as the potentiometer is adjusted.
