A parallel plate capacitor of capacitance C is connected to a battery and is charged to a potential difference V. Another capacitor of capacitance 2C is similarly charge to a potential difference 2V. The charging battery is now disconnected and the capacitors are connected in parallel to each other in such a way that the positive terminal of one is connected to the negative terminal of the other. The final energy of the configuration is
  • a)
    Zero
  • b)
    (3/2) CV2
  • c)
    (25/6) CV2
  • d)
    (9/2) CV2

Verified Answer
A parallel plate capacitor of capacitance C is connected to a battery ...
From the figure.
The net charge shared between the two capacitors
Q' = Q2 – Q2 = 4CV – CV = 3CV

The two capacitors will have some potential, say V'.
The net capacitance of the parallel combination of the two capacitors C' = C1 + C2 = C + 2C+ 3C
The potential of the capacitors 
The electrostatic energy of the capacitors
