Question

working principle of a

transformer?​

Answer 1

$\blue\bigstar\underline{\underline{\fbox{\blue{Answer:-}}}}$

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.

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. ... A voltage is then induced in the other coil, called the secondary or output coil.
