Four plates of the same area of cross-section are joined as shown in the figure. The distance each plate is `d`. The equivalent capacity across `A` and `B` will be

A

`(2epsilon_(0)A)/(d)`

B

`(3epsilon_(0)A)/(d)`

C

`(3epsilon_(0)A)/(2d)`

D

`(epsilon_(0)A)/(d)`

Text Solution

Verified by Experts

The correct Answer is:
B
The given arrangement is equivalent to the parallel combination of three identical capacitors. Hence
equivalent capacitance `= 3C = 3 (epsilon_(0)A)/(d)`
