What is transformer and how it works and tell me the ratings

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 of an alternating current (AC) power supply.
They work on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a coil of wire.
The ratings of a transformer include its voltage rating, current rating, and power rating.
For example, a transformer with a voltage rating of 120V/240V, a current rating of 10A, and a power rating of 2.4kVA can be used to step down 240V AC to 120V AC.
Transformers are commonly used in power distribution systems, electronic devices, and appliances.
