Question

Six equal capacitors each of capacitance C are connected as shown in the figure. The equivalent capacitance between points A and B is :

• A. 1.5 C
• B. C
• C. 2C
• D. 0.5C

Answer 1

Answer: (C)

2C

Here the bottom five capacitors will make balanced Wheatstone bridge circuit and equivalent capacitance is $C_{eq}=C$. Now the corresponding circuit is shown in figure.

Thus , $C_{AB}=C+C_{eq}$

$=C+C=2C$
