What is the 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 an electrical circuit.
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 power source, while the secondary winding is connected to the load.
The transformer operates based on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a nearby conductor.
Step-up transformers increase the voltage, while step-down transformers decrease the voltage.
Transformers are commonly used in power distribution systems, electrical appliances, and electronic devices.
Example: A power transformer used in a power distribution network to step down high voltage from power plants to a lower voltage suitable for household use.
