The energy stored in the two capacitors is less than the energy that was originally stored in C1 C 1. What has happened to the lost energy? A perfectly reasonable and not incorrect answer is that it has been dissipated as heat in the connecting wires as current flowed from one capacitor to the other.
Under ideal conditions, it is possible to transfer energy fromone capacitor to the other with efficiency approaching 100%. It ispossible to transfer gorge with efficiency considerably greater than100%.
Here no energy would be lost - when the charge is distributed evenly between the two capacitors, the remaining half of the energy will be stored in the magnetic field of the inductor. In reality there would be both inductance and resistance in the wires, so we would have an RLC circuit.
Your answer is wrong in the sense that the charge will not be equally divided between the plates of the two capacitors. And the reason is that the capacitors have different capacitances. In this case you need to apply Kirchoff's voltage rule to get the correct equation.
From what has been said, we expect the charge, Q = CVi Q = C V i on the first capacitor to distribute itself evenly between the two capacitors because they have the same capacitance. Therefore the final voltage over each capacitor will be the same and correspond to holding a charge of 1 2Q 1 2 Q.
If it were just 2 metal plates, charges would be equally distributed. But in a capacitor arrangement, the NET electric field between the plates (due to both plates) contribute to the voltage across them. (Δ V = − ∫ E ⋅ dl).
