Electrical Engineering XYZ MCQs
Rotating part of DC motor is known as:
- Carbon brush
- Starter
- Pole
- Armature
Correct answer: 4. Armature
Explanation: The armature is the rotating part of the DC motor. It typically consists of coils of wire wound around a metal core, which rotates in the magnetic field created by the poles. When electric current flows through these coils, magnetic forces are produced which interact with the magnetic field from the poles, thereby creating torque and causing the armature to rotate.
