Question

The equivalent capacitance between the points $A$ and $B$ is

• A. $2C_{0}$
• B. $C_{0}$
• C. $4C_{0}$
• D. $6C_{0}$

Answer 1

Answer: (A)

Rearranging the given circuit as,

Now, the arrangement seems to follow the principle of the Wheatstone bridge, again simplifying the circuit,

Calculating the equivalent capacitance using basic concepts of series and parallel combination of capacitors.
$C_{e q}=\frac{2 C_{0}}{3}+\frac{4 C_{0}}{3}=2C_{0}$
