Define transformers?

Question

Accepted Answer

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.

Transformers consist of two coils of wire, known as the primary and secondary coils, which are usually wound around a core made of iron or steel.
They work on the principle of electromagnetic induction, where a changing current in the primary coil induces a voltage in the secondary coil.
Transformers are used to step up or step down voltage levels in electrical systems, allowing for efficient transmission and distribution of power.
Examples of transformers include power transformers used in electrical substations, distribution transformers on utility poles, and voltage transformers in electronic devices.
