Answer / bala
generally capacitor gives infinite resistance to dc
components(i.e., block the dc components). it allows the ac
components to pass through.

Reactance of capacitor X = 1/(2πfc)
Since f=0, for dc frequency is zero.
So, Reactance X will be infinity for dc.
means capacitor blocks dc and allows only ac to pass

Answer / yuvi
Both capacitors and inductors are reactive components and
can be used only with AC circuits.

Answer / rakesh
Only high frequency
allowed to pass
through the capacitor,
& dc supply has
0(zero) frequency due
to this reason
capacitor work on only
ac.

Answer / krunal devi
for a capacitor in case of DC source applied over it first half of its period it goes on charging but it is not getting time for discharge because for DC source the current is constant . That's why it is working as break in dc circuit.
