Answer / chvnraja

if dc supply is given to transformer there will be no
change in the flux with time.so there is no emf induced in
the primary and secondary windings.and hence transformer
action will not take place.

Answer / anik chakraborty

Useles heat will be generated & if the i/p voltage is
sufficiently high then windings will burn out due to that heat

Answer / steven

Yes nothing transformers operate off of AC only.

Answer / muhammad shoaib

nothing happen it works as an open cct

Answer / roshan

if the in put of a transformer is DC then steady current will
flow due to which change in magnetic flux will not take place
& induced emf will not be produce & therefore the transformer
will not work

Answer / roshan

if the in put of a transformer is DC then steady current will
flow due to which change in magnetic flux will not take place
& induced emf will not be produce & therefore the transformer
will not work

Answer / preethi

yes in d.c no alternating supply ,no change of current with respective time no e.m.f induces as we know that transformer is a static device works on principle of mutual induction no flux means no induction.hence it not works with d.c. suply
