What is an electric transformer?

The transformer is the static device which works on the principle of electromagnetic induction. It is used for transferring the electrical power from one circuit to another without any variation in their frequency. In electromagnetic induction, the transfer of energy from one circuit to another takes places by the help of the mutual induction. i.e the flux induced in the primary winding is linked with the secondary winding.

Explanation:

A transformer is an electrical device that uses electromagnetic induction to pass an alternating current (AC) signal from one electric circuit to another, often changing (or "transforming") the voltage and electric current. ... Transformers are also used as a part of devices, like current transformers.
