TRANSFORMER:
what is transformer?
Transformer is a static device which transforms electrical energy from one circuit to another without any direct electrical connection and with the help of mutual induction between two windings and according toFaraday Law's Of Electromagnetic induction . It transforms power from one circuit to another without changing its frequency but may be in different voltage level.WORKING PRINCIPLE OF A TRASNFORMER:
Transformer works on the principle of mutual induction 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. accordingly an EMF is induced in the
secondary coil due to Faraday law's of electromagnetic induction.this induced EMF is directly proportional input applied.

Parts of transformer:
- Primary Winding of transformer - which produces magnetic flux when it is connected to electrical source.
- Magnetic Core of transformer - the magnetic flux produced by the primary winding, that will pass through this low reluctance path linked with secondary winding and create a closed magnetic circuit.
- Secondary Winding of transformer - the flux, produced by primary winding, passes through the core, will link with the secondary winding. This winding also wounds on the same core and gives the desired output of the transformer.
