Question

Explain the structure and function by drawing a diagram of an electric generator.

Answer 1

1. Structure:
   • It consists of a rectangular armature coil placed between the strong N and S poles of a magnet.
   • The ends of the coil are connected to two continuous slip rings, which maintain sliding contact with stationary carbon brushes.
2. Function:
   • When mechanical energy rotates the coil within the magnetic field, the magnetic flux linked with the coil continuously changes.
   • This induces an alternating current (AC) in the coil due to electromagnetic induction, which is drawn out through the brushes.
