In the given circuit, with steady current, the potential drop across the capacitor must be [IIT-JEE (Screening) 2001]
A) V
B) V / 2
C) V / 3
D) 2V / 3
Correct Answer:
C
Solution :
Moving anticlockwise from A \[-\,iR-V+2V-2iR=0\] or \[3iR=V\] or \[i=\frac{V}{3R}\] \[{{V}_{A}}-{{V}_{B}}=iR+V-V=iR\] Þ Potential drop across C =\[\frac{V}{3}\]
