Question
The Brushes of an Electric motor are made of a ____.
- Conductor
- Insulator
- Dielectric
- Semiconductor
Hint:
Brushes are used to serve electrical contact between the stationary points and the moving surfaces.
The correct answer is: Conductor
- Brushes are used to serve electrical contact between the stationary points and the moving surfaces. They are mainly used to transfer power from rotatory armature coils to stationary wires. They are used to reduce the damage of the motors.
- The brushes of an electric motor are made of carbon.
- The brushes of an electric motor are made of Conductor because it purpose is to serve electrical contact between the stationary points and the moving surfaces
