How many terminals or contacts of a rheostat
http://www.electricalterminology.com/rheostat/ WebRheostat as a Current Regulator In the diagram above, the effective resistance of the rheostat is between end terminal pin 3 and the wiper at pin 2. If pin 1 is left unconnected, the resistance of the track between pin 1 and pin 2 is open-circuited and has no effect on the value of the load current.

Like the potentiometer, the rheostat also consists of three terminals: terminal A, terminal B and terminal C.
WebWhy does rheostat have 3 terminals? Three terminals include two fixed terminals and a moving terminal (called a slider or wiper). Out of the two fixed terminals only one is used. As the slider moves over the resistive path, they change resistance in circuit and hence control the current in the circuit. How do you wire up A rheostat?
