What is transformer.?

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 in electrical power transmission and distribution systems.
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 receives electrical energy from the input circuit and produces a magnetic field.
This magnetic field induces a voltage in the secondary winding, which is connected to the output circuit.
Transformers are efficient and can transfer energy over long distances with minimal loss.
They are commonly used in power substations, electrical appliances, and electronic devices.
Step-up transformers increase the voltage, while step-down transformers decrease the voltage.
For example, a step-down transformer is used in power adapters to convert high voltage from the electrical grid to a lower voltage suitable for charging electronic devices.
