xc = 1/2* π*f*c .

f = 0.

So xc is 1/0 is infintity that why block VDC current flow negligible if the capacitor is in series with VDC.

Hi nagashree, your explanation is simple and clear.

Through formula...in dc ckt freq is zero

We-know-that Xc=(1/2*pi*f*c)

f=0 therefore Xc=infinity

Capcitor blocks dc flow, so reactance value for DC circuit is infinite.
