Homework Help: Capacitance, charge and potential

  1. Mar 17, 2010 #1
    1. The problem statement, all variables and given/known data

    The battery has a potential difference of 20 V. Find: a. the equivalent capacitance of all of the capacitors and b. the charge stored on that equivalent capacitance. Find the potential across and charge on c. capacitor 1, d. #2, and e. #3.

    See paint file for an attempt at a diagram.

    2. Relevant equations
    q = C V

    3. The attempt at a solution

    I have done parts a and b, but I don't know how to go from there.
    I got Ceq = 3 x 10-6F
    and q = 6 x 10-5 C
    Once I have the equivalent capacitance, does that help me with parts c, d, and e? Or do I use the individual capactitances(and if so, with what q and V if I have to find both)?
