Explain the working of AC electronic generator with a neat diagram.

Definition: AC generator is the device which converts the mechanical energy into the electrical energy.

Principle: 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.

Working:

i. A rectangular coil is held between the poles of two curved permanent magnets.

ii. As the coil rotates the Magnetic flux(due to permanent magnets) passing through the coil changes.

iii. Due to change in the magnetic flux, the induced current is generated in the coil.

iv. Thus converting the Mechanical Energy (Rotation of Coil) into the electrical energy(currently produced in the coil.
