Question: A parallel plate capacitor is made by stacking $ n $ equally spaced plates connected alternately. If the capacitance between any two plates is $ C $ then the resultant capacitance is [NCERT 1971; DPMT 2001; MP PMT 2003; AIEEE 2005]

Options:

A) $ C $

B) $ nC $

C) $ (n-1)C $

D) $ (n+1)C $

Show Answer

Answer:

Correct Answer: C
