Transformers

  • A transformer is a device that changes voltage  from one value to another.
  • Power at the input end  is equal to the power at the output end.
  • Only the voltage will increase or decrease.

Principle:-

Transformers work on the principle of Mutual induction.

Mutual Induction :- Suppose there are 2 inductors if some current flows through coil(1) ,there will be change in the current as a result there will be change in the magnetic flux, as a result there will be  change in the magnetic flux in the coil (2) and because of which emf is induced in the coil(2).
