Question

A transformer works on the principle of
(a) self induction
(b) electrical inertia
(c) mutual induction
(d) magnetic effect of the electrical current

Answer 1

Answer:

(c) Mutual induction.

• Transformers work on the principle of mutual induction.

Hope it helps you.

Answer 2

Answer:

A transformer consists of two electrically isolated coils and operates on Faraday's principal of “mutual induction”, in which an EMF is induced in the transformers secondary coil by the magnetic flux generated by the voltages and currents flowing in the primary coil winding.
