Question

b) Write the principle of AC generator.
​

Answer 1

principal of AC generator: the AC electric generator works on the principle that when a straight conductor is moved in a a magnetic field then the current is induced in the conductor .

Answer 2

AC GENERATOR. 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.
