Answer / alok ranjan

when dc supply is given to the transformer momentary emf is generated at the secondary side and collapse suddenly.
because flux does not change periodically due to dc supply.

Answer / tirupathi rao

transformer winding will get damaged, why because for Dc flux produced will be zero,emf generated in winding i zero so difference in supply voltage and emf produced high. as the transformer winging resistance also less so high current flow through winding so transformer get damaged

Answer / arun singh mehra

when a dc supply is given to a transformer initially a flux is generated in primary windings but there is no emf produced because of e=-d(change in flux)/change in time.and there is no
output produced in the secondary output.

Answer / dineshkumar

when the dc supply passes through the transformer winding transformer core will gets magnatised (electro magnetic energy generated)
