What is an electric generator?

Electric generator is the device which converts the mechanical energy into the electrical energy.

It works on the Faraday’s law of the Electromagnetic Induction which says that whenever a conductor is placed in a varying magnetic field, EMF is induced and this induced EMF is equal to the rate of change of flux.

Electric generators are of two types A.C generator and D.C generator. Figure below shows the A.C generator.
