Question

Capacitance of all the capacitors is same and equal to C. The equivalent capacitance of the system is

• A. $\frac{C}{3}$
• B. $\frac{3C}{2}$
• C. $\frac{2C}{3}$
• D. 2C

Answer 1

The correct option is C $\frac{2C}{3}$


The system can be simplified as shown in the figure above.
By symmetry potential of node a & b will be same.
Similarly potential of node c & d is same and of e & f is same.

So, from the figure, we get the net capacitance as $\frac{2C}{3}$
