A potentiometer is a three-terminal resistor with a sliding or rotating contact that kinds an adjustable voltage divider. Potentiometers are generally used to regulate electrical alerts, comparable to quantity or brightness. They will also be used as sensors to measure the place of a mechanical system.
To hook up a potentiometer, you will have to attach the three terminals to an influence supply and a load. The facility supply could be a battery, an influence provide, or one other voltage supply. The load could be a resistor, a light-weight bulb, or one other electrical system.
