However, the two still achieve the same function. While a potentiometer uses a third terminal to serve as the adjustable part, the rheostat uses a slider to vary resistance. If the slider isn't moved, the rheostat functions as a fixed resistor. A rheostat is connected in a circuit by having the two leads connected in series with the load.
