What is transformer? How many types of transformer, nd works, construction

Question

Accepted Answer

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
There are two main types of transformers: step-up transformers and step-down transformers.
Step-up transformers increase the voltage of the input power supply, while step-down transformers decrease the voltage.
Transformers are made up of two coils of wire, called the primary and secondary coils, wrapped around a magnetic core.
When an AC current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.
Transformers are used in a variety of applications, including power distribution, electronic devices, and audio equipment.
