Question
The equivalent capacitance of the combination of three capacitors, each of capacitance C shown in figure between points A and B is
-
-
-
- 2C
The correct answer is: 2C
In the arrangement shown both plates of capacitors are joined to point Hence, it does not act as a capacitor and is superfluous. Now and are in parallel, hence
