A parallel plate capacitor is made by stacking n equally spaced plates connected alternatively. If the capacitance between any two adjacent plates is 'C' then the resultant capacitance is

A

nC

B

`C/n`

C

`(n+1)C`

D

`(n-1)C`

Text Solution

Verified by Experts

The correct Answer is:
D
When n equally spaced plate are connected alternatively, (n-1) capacitors, each of capacity C are formed . As they are joinied in parallel, `therefore C_(eq) = (n-1)C`
