in this video i will tell you about ac generator. AC generators or alternator 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-
1. the number of turns in the coil.
2. strength of the field.
3. the speed at which the coil or magnetic field rotates.
