With n parallel plates each of same area A and separated by equal distance d with air or vacuum between the plates, What is the effective Capacity?


Let me see who can give the right answer with proper explanation...
​

Answer 1

Answer:

Suppose the pair of plates is connected to positive terminal of the battery and the pair of plates Q is connected to the negative terminal of the battery.

From figure, it is clear that we have two capacitors C

1 .2 and C

1 . Positive plates of C

2. are connected to positive plate of C

and negative plate to negative. Therefore C

1

and C

2

are in parallel.

So, C
