When capacitors is arrange in series (3 capacitors), the equivalent capacitance C is
C = C1 + C2 + C3
1/C = 1/C1 + 1/C2 + 1/C3
C = QV1 + QV2 + QV3
C = CR1 + CR2 + CR3
When capacitors in parallel (3 capacitors), the equivalent capacitance is
C = C1 + C2 + C3
C = 1/C1 + 1/C2 + 1/C3
C = QV1 + QV2 + QV3
C = QV1 + QV2 + QV3
The energy stored in the capacitor can be find by using this equation EXCEPT
1/2QV
1/2Q2/C
1/2CV2
1/2RC2
