Transformer concept

Accepted Answer

A transformer is a static 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 made of iron or steel.
The primary coil is connected to the input voltage source, while the secondary coil is connected to the output load.
The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines the voltage transformation ratio.
Examples of transformers include power transformers used in electrical substations and distribution transformers used in residential areas.
