Answer Posted / suresh kumar k
The question itself is a little wrong, infact the question
should be "Why we will not apply DC to a Transformer, if it
applies what happens?
The answer is, there is no inductance effect produced in DC
as such in AC. If we apply a DC voltage to the primary of
the winding then there will be no Back EMF produced in the
primary winding because of lack of self inductance in the
winding for DC. Hence huge currents of the order of
thosands of Amps flow in the Pri. winding and leads to fire
in the winding. Also Since there is no mutual inductance
effect in secondary of the winding there will be no induced
EMF in secondary.
