Choose the right answer:
a)A capacitor can conduct a dc circuit ,but not an inductor.
b)In a dc circuit ,the inductor can conduct but not a capacitor.
c)In a dc circuit, both the capacitor and inductor cannot conduct.
d)The inductor has a infinite resistance in a dc circuit.

Dear Student,
A capacitor can conduct only while charging and discharging and hence will not conduct in dc current. An inductor can act as a short circuit in dc and hence will conduct in dc.
Reactance of an inductor is
 XL=ωL=2πfLwhere,ω=2πf, f is the frequency of the signalif f =0XL=0
