What is a transformer

Question

Accepted Answer

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

Transformers are commonly used in power distribution systems to step up or step down voltage levels.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding is connected to the input voltage source, while the secondary winding is connected to the load.
The transformer operates based on the principle of electromagnetic induction, where a changing current in the primary winding creates a changing magnetic field, which induces a voltage in the secondary winding.
Transformers are efficient and allow for the transmission of electrical energy over long distances with minimal losses.
Examples of transformers include power transformers used in electrical substations, distribution transformers on utility poles, and small transformers in electronic devices.
