A transformer is a device which convert low ac voltage into high ac voltage and vice virsa. It is of two type 1.step down 2.step up Principal = it is based on mutual induction means whenever the magnetic flux link with a coil change a induce emf produce in a neighbouring coi.

A transformer is a device that convert low a.c. voltage to high a.c. voltage or vice versa. There are two types of transformer i.e. step up and step doen .TRANSFORMER IS BASED ON THE PRINCIPLE OF MUTUAL INDUCTION. IT STATES THAT WHENEVER THERE IS INDUCED EMF IN SECONDARY COIL DUE TO CHANGE IN INDUCED CURRENT IN THE PRIMARY COIL.
