What is transformer

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 the voltage of an alternating current (AC) signal.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding receives electrical energy from a power source, while the secondary winding delivers the transformed energy to the load.
Transformers are essential in power distribution systems to transmit electricity efficiently over long distances.
They are also used in electronic devices like chargers, adapters, and power supplies to convert voltage levels.
Examples of transformers include step-up transformers, step-down transformers, and autotransformers.
