ü Transformer is a Device that transfer electric
power
ü Transformer operates on ac supply
ü It can increase the voltage or current
ü If voltage is increasing the current is
decreasing
ü And if current is increasing the voltage is
decreasing
ü Without change of frequency and increasing power
ü It has two coil or more (primary and
secondary)
