A capacitor of capacity $C_1$ is charged to the potential of $V_0$. After disconnecting with the battery, it is connected with a neutral capacitor of capacity $C_2$ as shown in the adjoining figure. The ratio of energy of system before and after the connection of switch $S$ will be
$\frac{{{C_1} + {C_2}}}{{{C_1}}}$
$\frac{{{C_1}}}{{{C_1} + {C_2}}}$
$C_1C_2$
$\frac{{{C_1}}}{{{C_2}}}$
