Answer Posted / alok ranjan
when dc supply is given to the transformer momentary emf will be generated at the secondary side and will collapse suddenly.
because flux does not change periodically due to dc supply.it changes only when it is switched from off to on or on to off.
primary coil may burn but Burning or not burning of primary depends on design consideration whether it can carry current according to applied voltage or not.because for dc,inductance will be zero so resistance of primary will be less than ac impedance, so current and I^2R loss will increase.
