Electromagnetic induction is used in the generation of electricity. The alternating current generator is an electromagnetic devise which transforms mechanical energy into electrical energy. Simple a.c. generator Consists of a rectangular coil of wire that is mounted...
A transformer is a device that changes a high alternating voltage at a low current to a low alternating voltage at a high current or vice versa. It is a useful device used for: electrical power transmissions from power stations to the consumer loads; regulating...
Electromagnetic induction is the phenomenon of inducing an e.m.f. into a circuit due to a changing magnetic field. Faradays’ experiments i. Iron Ring Experiment: two coils of insulated copper wire are wound round a soft iron ring. The ends of coil A are connected to a...
