Two idential capacitors are joined in pa...

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

The charges on the free plated connected together are destoyed.

B

The energy stored in the system increases.

C

The potential difference between the free plates is 2V.

D

The potential difference remains constant.

Text Solution

Verified by Experts

The correct Answer is:
C
When the two capacitor charged to same potenital are connected in series, then total potential difference `V = V_(1) +V_(2) = V + V =2V`
