Generation and transmission MCQ with Answers

1) Which principle the transformer works?

Answer is:

Mutual induction

Explanation:

The basic principle on which the transformer works is Faraday's Law of Electromagnetic Induction or mutual induction between the two coils. It works on the alternating current only because an alternating flux is required for mutual induction between the two windings.
