why dc power can not be used in transformer?
Answer Posted / jinen dand
Transformer works on Mutual Induction principle. Mutual
induction principle works only on Ac suppy.
So dc power cannot be used in transformer.
If dc power is supplied to transformer following things
will happen
1. if winding resistance is low then according to ohm law
high current will flow through winding which will cause
high temp rise if supply sustains then winding may get
damage.
2. If winding resistance is high compare to applied voltage
then only contant flux around winding will be there.
It is very good question..........
