WebA potentiometer is a manually adjustable variable resistor with 3 terminals. Two of the terminals are connected to the opposite ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The potentiometer essentially functions as a variable resistance divider. 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.
