Questions  

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

a
C
b
n C
c
(n+1) C
d
(n - 1) C

detailed solution

Correct option is D

For n plates joined alternately, there will be (n - 1) capacitors connected in parallel Fig. Their equivalent capacitance will be Ceq=(n−1)C.
