Answer Posted / 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.
