Question

A parallel plate capacitors is formed by stacking n equally spaced plates connected alternately. If capacitance between 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 $(n-1)C$

There will have $(n-1)$ capacitors. As they are connected alternately so they are connected in parallel. thus resultant capacitance is $C_{eq}=(n-1)C$.
