Capacitors - Technical MCQs

Q1:

What is the reactance value for a capacitor installed in a dc circuit?

A zero

B moderate

C infinite

D cannot tell

ANS:C - infinite

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.
