Question
Two similar condensers are connected in parallel and are charged to a potential V. Now these are separated out and are connected in series as shown. Then


Options
A.the energy stored in the system increases
B.the potential difference between free plates may becomes zero.
C.the potential difference between free plates may becomes 2V.
D.the charge on the plates mutually connected nullifies.
Solution
the potential difference between free plates may becomes 2V.

When terminal B is connected with terminal C
VA − VD = 2V
When terminal B is connected with terminal D
VA − VC = 0
The energy stored in the system remains same.

When terminal B is connected with terminal C
VA − VD = 2V When terminal B is connected with terminal D
VA − VC = 0 The energy stored in the system remains same.
