State A.C. generator underlying principle?
उत्तर
Underlying principle of an A.C. generator
The underlying principle responsible for the working of an Α.C. generator is electromagnetic induction. According to this principle, if a conductor is placed in a varying magnetic field, then current is induced in the conductor.
