A rheostat is a two-terminal variable resistor; a potentiometer is a three-terminal variable.
You could wire a pot to act as a rheostat, electrically.
Most pots are very low wattage; the rheostat term is used here because most rheostats in this application are wirewound and can handle the higher lamp currents directly. |
