WebThe rheostat has three terminals as it is used as a potential divider, and it is used for eliminating the possibility of the open circuit due to the wiper movement. How to test a … 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?
