Calculate charge and capacitance

[Saundaz]

Homework Statement

Three capacitors are connected in series, C1 = 4.5 mF, C2 = 7.5 mF, and

C3 = 10 mF, and connected to a 150V d.c. supply. Calculate:

(a) the total capacitance;

(b) the charge on EACH capacitor;

(Comment upon this answer)

(c) the p.d. across C3;

Homework Equations

Can someone explain this to me? As this is my weakest part in Physics, and i don't really understand it.
