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 the voltage in electrical power transmission and distribution systems.
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 the input circuit and produces a magnetic field.
This magnetic field induces a voltage in the secondary winding, which is connected to the output circuit.
Types of transformers include power transformers, distribution transformers, autotransformers, isolation transformers, and instrument transformers.

Accepted Answer

Transformer is a static AC Machine, that transfer Power from one circuit to another by stepping up and down the voltage and current without changing the supply frequency.
