. 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: (n - 1)C
B: (n + 1)C
We know that,
n plates connected alternately give rise to (n–1) capacitors connected in parallel,
Resultant capacitance =(n–1)C.
Hence, Option A ic correct i.e, (n-1)C
