Answer / najeeb

If DC voltage is applied to the primary of a transformer the
flux produced in the transformer core, will not vary but
remain constant in magnitude therefore no emf will be
induced in the secondary winding except at the time of
switching on.Also there will be no self induced emf in the
primary winding to oppose the applied voltage and since the
resistance of the primary winding is quite low heavy current
will flow through it which may result in burning out of
primary winding

Answer / shaik rasool

transformer will be burn.because of 2 reasons
1. obsence of self induced emf.
2.the flux is nt alternative ,bcz the flux is not very

Answer / pradyumna chandra panda

Primary winding of transformer has very low resistance it act a indictive load on ac supply so it is easily stand . but legging current is not possible in dc supply, the primary will burn when it connected with dc supply due to small resistance. And mitual induction is not possible in dc supply so no emf will induced in secondary winding. N.B Armature resistance of dc motor is very low but it can stand due to back emf.

Answer / najeeb

the transformer will burn as the resistance of the winding
is very low. and will act as a short circuit

the out voltage is zero.

Transformer will be primary widing bure.

Answer / sandeshg

when DC supply is given to the transformer transformer winding
s gets heated up because of unidirectional current flows
through the conductor. basically transformer needs varying
source(AC)for induction(basic principle) but DC is
unidirectional.

Answer / rangan

WHEN DC SUPPY IS GIVEN TO THE TRANSFORMER THERE WILL NO
OPPOSITION OF FLUX IN THE TRANSFORMER

Answer / prabakaran

THE TRANSFORMER AS A WINDING NOT STORAGE(CAPACITANSC) ONLY
SEND TO ONE FORM OF TO ANOTHER FORMS SUPPLAY SO
TRANSFORMER NOT ALLOWED IN THE DC SUPPLAY
