1K Potentiometer 7mm ShaftThe 1K Pot Potentiometer is a three terminal variable resistor that is used to vary or change the resistance. It is used to change different parameters in an electronic circuit, such as voltage, current, and so on. The 1K Potentiometer is a passive electronic component that has two end terminals with a resistive element and the sliding contact called the wiper acts as the third terminal. Two other terminals present are used to facilitate stabilized
