Question

basic principle involved in 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.

    Alternating voltage may be generated by rotating a coil in the magnetic field or by rotating a magnetic field within a stationary coil. The value of the voltage generated depends on-

•  the number of turns in the coil.

• strength of the field.

• the speed at which the coil or magnetic field rotates.
