Answer
A electric generator is a machine that converts mechanical energy into electrical energy. The working principle of generator is the law of electromagnetic induction and the law of electromagnetic force. The generator is mainly made up of stator and rotor.
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.
