Two idential capacitors are joined in parallel, charged to a potential `V` and then separated and then connected in series i.e. the positive plate of one is connected to negative of the other

A

10V

B

20V

C

40V

D

15V

Text Solution

Verified by Experts

The correct Answer is:
C
First case, they are joined in parallel and ini the second case, they are joined in series,
`therefore P.D.` in first case=20V, the P.D. in second case=40V.
