Question

what is the working principle of transformer?​

Answer 1

Answer:

Working principle: it works on the principle of mutual induction of two coils or Faraday Law's Of Electromagnetic induction. When current in the primary coil is changed the flux linked to the secondary coil also changes.hence an EMF is induced in the secondary coil due to Faraday law's of electromagnetic induction.

Explanation:

Hope it helps..

Answer 2

Answer:

Definition : Transformer is a static device which convert electrical power from one circuit to another without changing it's frequency. it step up (or step down )the level of AC voltage and current.

Working Principle : it works on the principle of mutual induction of two coils or Faraday law's of Electromagnetic induction. .....
