PRINCIPAL OF TRANSFORMER

Question

Accepted Answer

The principle of a transformer is based on electromagnetic induction, where a changing current in one coil induces a voltage in another coil.

Transformers work on the principle of mutual induction between two coils.
The primary coil carries the input current and creates a changing magnetic field.
This changing magnetic field induces a voltage in the secondary coil, which produces the output current.
Transformers are used to step up or step down voltage levels in electrical systems.
Efficiency of a transformer is determined by its design and materials used.
