why dc power can not be used in transformer?
Answer Posted / rajesh babu
we cant use dc power in a transformer.there are two main
reasons supporting above statement
1)there will be no action of transformer(as it works on
principle of mutual induction)
2)winding of the transformer acts as inductor&it acts as
short circuit for DC
inductive reactance XL=2*PI*F*L
DC HAS ZERO FREQUENCY so XL=0,HENCE IT ACTS AS SHORT CIRCUIT
Deu to this winding of the transformer may burns out.
