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 levels in electrical power transmission and distribution systems.
They consist of two or more coils of wire, known as windings, which 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 core provides a path for the magnetic flux generated by the alternating current in the primary winding to link with the secondary winding.
The ratio of the number of turns in the primary winding to the number of turns in the secondary winding determines the voltage transformation ratio.
Step-up transformers increase the voltage level, while step-down transformers decrease it.
Transformers are highly efficient and can transfer electrical energy over long distances with minimal losses.
They are commonly used in power substations, industrial facilities, and residential applications.
Examples of transformers include distribution transformers, power transformers, and autotransformers.
