Working principle of Transformer

Question

Accepted Answer

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

Transformers work on the principle of electromagnetic induction.
They consist of two or more coils of wire, known as windings, which are wound around a common magnetic core.
The primary winding is connected to the input voltage source, while the secondary winding is connected to the load.
When an alternating current (AC) flows through the primary winding, it creates a changing magnetic field in the core.
This changing magnetic field induces a voltage in the secondary winding, which is then used to power the load.
Transformers can step up or step down the voltage depending on the ratio of turns in the primary and secondary windings.
They are commonly used in power distribution systems to increase or decrease the voltage levels for transmission and distribution.
Examples of transformers include power transformers, distribution transformers, and instrument transformers.
