Homework Help: Calculate charge and capacitance

  1. Jul 20, 2017 #1
    1. The problem statement, all variables and given/known data

    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;

    2. Relevant equations
    Can someone explain this to me? As this is my weakest part in Physics, and i dont really understand it.

    3. The attempt at a solution
    Tried to do research but i don't know wha tim looking for/at
