A parallel plate capacitor is made by stacking `n` equally spcaed plates connected alternately. If trhe capacitance between any two plates is C, then the resultant capacitance is

`(n-1)C`

`(n+1)C`

`C`

`nC`

Text Solution

Verified by Experts

The correct Answer is:

Each plate is taking part in the formation of two capacitors except the plates at the ends.
These capacitors are in parallel and n plates form (n-1) capacitor.
Thus, equivalent capacitance between A and B=(n-1)C.
