In both circuits, $C_1 = 10 \mu$F, $C_2 = 20 \mu$F, $C_3 = 30 \mu$F, and the potential difference across the circuits is $V = 15 \text{ V}$.

In the series circuit, the amount of energy stored in capacitor $C_1$ is

the energy stored in capacitor $C_3$.

In the parallel circuit, the amount of energy stored in capacitor $C_1$ is

the energy stored in capacitor $C_3$.
