The final energy storage of the series capacitor

The energies stored in these capacitors are U 1 = 1 2 C 1 V 1 2 = 1 2 (12.0 μ F) (4.0 V) 2 = 96 μ J, U 2 = 1 2 C 2 V 2 2 = 1 2 (2.0 μ F) (8.0 V) 2 = 64 μ J, U 3 = 1 2 C 3 V 3 2 = 1 2 (4.0 μ F) (8.0 V) 2 = 130 μ J. The total energy stored in this network is U C = U 1 + U 2 + U 3 = 96 μ J + 64 μ J + 130 μ J = 0.29 mJ.
