Question

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

• A.
• B.
• C. $( n - 1 ) C$
• D. $( n + 1 ) C$

Answer 1

Answer: (C)

$( n - 1 ) C$

Answer 2

The given arrangement becomes an arrangement of $( n - 1 )$ capacitors connected in parallel. So $C _ { R } = ( n - 1 ) C$
