Answer / bibek

in dc supply there is no rate of change of current... so induction is zero.. bt transformer is works on the principle of induction.. as there is no induction the o/p is zero..

Answer / sethu ramanj

1. There is no rate of change of current.
2. When we supply dc current to a inductor,the inductor just
act as a resistor. Due to low resistance of inductor more
current will flow through it and it will damage the inductor
coil and power devices.

if i am wrong plz correct me!!
