What is the transformer

Question

Accepted Answer

A transformer is a 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.
The primary coil is connected to the input voltage source, while the secondary coil is connected to the output load.
Transformers are commonly used in power distribution systems to step up voltage for long-distance transmission and step down voltage for consumer use.
Examples of transformers include distribution transformers, power transformers, and instrument transformers.
