Transformer working principle

Question

Accepted Answer

Transformer works 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, wrapped around a core made of iron or steel.
When an alternating current flows through the primary coil, it creates a changing magnetic field around the core.
This changing magnetic field induces a voltage in the secondary coil, causing current to flow and transfer electrical energy.
Transformers are used to step up or step down voltage levels in power distribution systems.
Example: A step-up transformer increases voltage for long-distance power transmission, while a step-down transformer decreases voltage for household use.
