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

`nm`

B

`n/m`

C

`n n^(2)`

D

`(n-1)x`

Text Solution

Verified by Experts

The correct Answer is:
D
`(n-1)` capacitors are n
All capacitors are connected in paralllel because plates are connected alternately
`therefore" Total capacitance "=(n-1)x`
