Question

Which principle the transformer works?​

Answer 1

Answer:

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. ...

Answer 2

Answer:

A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to "step up" or "step down" voltages and works on the magnetic induction principle.
