To determine

To Explain:Working of electric generator by using the concept of electromagnetic induction.

Explanation of Solution

Introduction:

Electromagnetic induction is a process of using magnetic field to produce (or generate) voltage and current (in a complete circuit).

Electromagnetic induction produces a voltage or EMF, i.e., electromagnetic induction across the electrical conductor.

Electric generatorswork on the principle of electromagnetic induction. In an electric conductor, electromagnetic field is induced in a conductor (or coil) when there is change in the magnetic field around it. EMF produces current when the generator is in the circuit. Induced EMF and current reverse in the direction the same asthe armature rotates through $180°$ .The electromagnetic field that is produced is proportional to the rate at which the flux changes.

Conclusion:

Theelectric generator’sworking is based on the concept of electromagnetic induction.
