Product Description A potentiometer is an adjustable electronic component. It is composed of a resistor and a rotating or sliding system. Manually adjust the rotating shaft or sliding handle to change the moving contact on the resistor body The resistance between the moving contact and any fixed terminal is changed, thus changing the voltage and current. Potentiometer is a synchronous adjustment potentiometer made of resistor substrate. Its role in the circuit is to obtain the output voltage that is in a certain relationship with the input voltage (external voltage), so it is called a potentiometer. Sliding resistor is a potentiometer commonly used in the laboratory. This potentiometer has large volume, large power, visual sliding, and can also be used as a current limiter.
