What is Transformer ?

Question

Accepted Answer

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

Transformers are used to increase or decrease voltage levels in electrical circuits.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.
Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels.
Transformers are commonly used in power distribution systems to transmit electricity over long distances.
They are also used in electronic devices to convert voltage levels for different components.
