What is working of transformer and it's working principle? Application of transformer

Question

Accepted Answer

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

Transformers work on the principle of electromagnetic induction
They consist of two coils, primary and secondary, wound around a common magnetic core
When an alternating current is passed through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil
Transformers are used in power transmission and distribution, voltage regulation, and electrical isolation
Step-up transformers increase voltage while step-down transformers decrease voltage

Accepted Answer

Transformer is a static device, which transforms the electrical energy from one circuit to other circuit without changing any frequency.
