What is the 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 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 a power source, while the secondary winding delivers the transformed energy to the load.
Transformers work based on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a nearby conductor.
They are essential in stepping up the voltage for long-distance transmission to reduce power losses and stepping down the voltage for safe utilization in homes and industries.
Examples of transformers include power transformers, distribution transformers, instrument transformers, and autotransformers.
