If you give DC supply to AC coil ,it may burn out as
inductance is absent for DC

Answer / kashi gujjar

In case of AC supply:
the coil will have inductive reactance as X=2*pi*f*L

In case of DC supply:
the coil will have zero inductive reactance i.e X=0.

so in case of d.c a large amount of current will flow because coil will offer nearly zero resistance to current as a result of which the coil will damage.
