What is the working principle of transformer?

Solution
Transformer :
It is a static electrical machine that is used for either increasing or decreasing the voltage level of the AC supply with a corresponding increase or decrease in the current at a constant frequency.
Working principle :
- The working of the transformer is based on the mutual inductance principle.
- Mutual inductance principle states that, when an alternating voltage is applied to the primary winding of the transformer, an alternating flux is produced in the core.
- This flux links both the winding magnetically and induces emf in the secondary coil according to Faraday’s law of electromagnetic induction.
