Question

what is the function of brushes in an electric generator

Answer 1

A brush is a device which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electricmotors, alternators and electric generators.

Answer 2

Function of Brushes in Electric Generator:

The function of brushes in the electric generator are as follows –

1. Brushes are used to conduct current in the electric generator, be it either AC generator or DC generator.

2. In AC generators, they picks up the current and conducts Alternating current in the generator, being the exciter and provide excitation

3. In DC generators, they collects Direct current. And conducts current for the electric generator forming the circuit from commutator to external circuit.
