What will happen if dc supply is given to primary of transformer ?
First of all, transformer wont work on dc supply and we wont get any induced emf in secondary because there won't be any change in flux with dc supply, hence there won't be faraday's law of electromagnetic induction.
With dc supply, there is no inductance only a small value of resistance will be offered,so the primary current will be quite high and much more than rated primary load current.This will burn the insulation of coil and transformer will be damaged.
