Question

Name the electric device which converts mechanical energy into electrical energy. Draw the labelled diagram and explain the principle involved in this device.

Answer 1

An electric generator converts mechanical energy into electrical energy.



MNST → Rectangular coil

A and B → Brushes

C and D → Two slip rings

X → Axle, G → Galvanometer

The principle of working of an electric generator is that when a loop is moved in a magnetic field, an electric current is induced in the coil. It generates electricity by rotating a coil in a magnetic field. The above figure shows a simple AC generator.
