Here is a simple explanation :
There will be no current through a capacitor is the voltage across the ends is not changing with respect to time.
So irrespective of the circuit whether its an AC or a DC if the voltage across the ends of a capacitor changes with time then there will be a current through it and hence there will be a change in the current in the external circuit to which it is connected.
It is a Known fact that AC changes its polarity depending upon the supply frequency and hence there will be a change in the circuit current .
But in D.C there is no change in voltage across the capacitor normally. And hence there will be no change in the current in the external circuit .
I hope this explanation will help, if you feel its wrong please comment below.
