Question
In the given circuit, with steady current, the potential difference across the capacitor must be
Options
A.V
B.V/2
C.V/3
D.2V/3
Solution
In steady state conditions, no current will flow through the capacitor C. Current in the outer circuit,
Potential difference between A and B
VA - V + V + iR = VB
∴ VB - VA = iR =
Note : In this problem charge stored in the capacitor can also be asked, which is equal to q = C
with positive charge on B side and negative on A side because VB > VA.
