  TRANSFORMERS  Transformer? ã A static piece of Equipment ã With 2 or more windings in it ã Conductively disjoined windings ã Magnetically coupled windings with a time varying magnetic field ã Meant for voltage/ Power transfer from one place/ level to the other.  Faraday’s Laws   ã Whenever a conductor cuts magnetic field, an emf is induced in it. ã The magnitude of the induced emf is equal tothe rate of change of flux  Lenz’s Law   ã Electro magnetically induced current will oppose the very cause which produces it. VENo loadiV- E = no load loss of a Transformer.
