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 charged 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
- zero
- \(\frac{3}{2} \mathrm{CV}^{2}\)
- \(\frac{25}{6} \mathrm{CV}^{2}\)
- \(\frac{9}{2} \mathrm{CV}^{2}\)
Answer
(B) 3 2 CV ^ 2
