Question

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

Answer 1

Answer: (A)

The equivalent circuit diagrams are as shown in the figure (a) and (b).

The equivalent capacitance between $A$ and $B$ is
$\frac{1}{C_{eq}}=\frac{1}{3C}+\frac{1}{3C}$
$\frac{1}{C_{eq}}=\frac{2}{3C},C_{eq}=\frac{3}{2}C=1.5C$
