Answer Posted / nagaswathi
generally transformer is a static device, by passing current
mangetic flux is produced which induces emf in secondary
with respect to change in flux which varies with time as
d.c. is not a time varient emf is not produced thus the
basic principle of transformer fails
2.as a result of this the windings of transformer burns out.
