Question

Principle & working of AC generator

Answer 1

Principle : A.C. generators or alternators (as they are usually called) operate on the same fundamental principles of electromagnetic induction as D.C. generators. the speed at which the coil or magnetic field rotates.

An alternating current (ac) generator is a device that produces a potential difference . A simple ac generator consists of a coil of wire rotating in a magnetic field. Cars use a type of ac generator called an alternator to keep the battery charged and to run the electrical system while the engine is working.
