Question

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. $(n+1)C$
• C. $C$
• D. $nC$

Answer 1

The correct option is A $(n-1)C$

$n$ plates connected alternately give rise to $(n–1)$ capacitors connected in parallel $\therefore$, Resultant capacitance $=(n–1)C$.
