In the given figure, the equivalent capacitance between points A and B is

A) 1.5 C

B) 2 C

C) 3 C

D) 6 C

Correct Answer: A

Solution :

[a]: The equivalent circuit diagrams are shown in the figure (i) and (ii). The equivalent capacitance between A and B is \[\frac{1}{C & {{ & }_{eq}}}=\frac{1}{3C}+\frac{1}{3C},\frac{1}{{{C}_{eq}}}=\frac{2}{3C},{{C}_{eq}}=\frac{3}{2}C=1.5C\]
