- Q1. Working of transformer
- Ans.
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 have two coils, primary and secondary, wound around a common magnetic core
When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil
The voltage in...
