Transformers working principle

Question

Accepted Answer

Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.

Transformers have two coils of wire, known as primary and secondary coils, which are wound around a core made of ferromagnetic material.
When an alternating current flows through the primary coil, it creates a changing magnetic field around the coil.
This changing magnetic field induces a voltage in the secondary coil, causing current to flow through it.
The ratio of the number of turns in the primary and secondary coils determines the voltage transformation ratio of the transformer.
Transformers are used to step up or step down voltage levels in electrical power distribution systems.
Examples of transformers include power transformers used in substations and distribution transformers used in residential areas.
