transformer work on principle of induction,that changing
flux which occur in a.c supply.
dc magnetic flux of pramary winding not cut with secondory
winding by air gap.
Transformer cannot work on dc supply because dc voltage has
no frequency when we give dc voltage to primary winding
then will not produce e.m.f. and so low resistance cause
high current flow in the primary winding and finally
winding will burn.
