Capacitor

[parkicar]

Voltage 12v
Capacitor Values of series Circuit
1st (uf) 56
2nd (uf) 68
3rd (uf) 82

a)Total Capacitance
b)Total Charge in the Circuit, and Charge in each Capacitor
c)Voltage across each Capacitor
d)total energy stored in the circuit, and the energy stored in each capacitor

Ive got my full workings out but im completly messed up and confused it would be brilliant if someone could show us a easy way on doing this or showing me the answers
I first Got for part a one was
Total capacitance was 22.342 microfarads i think

Cheers if you can help thanks
