Homework Help: Finding charge/capacitance.

  1. Oct 10, 2008 #1
    1. The problem statement, all variables and given/known data

    Four capacitors are connected as shown in the figure below:

    3. The attempt at a solution

    (a) Find the equivalent capacitance between points a and b.
    I found it to be 6.54μF.

    (b) If ΔVab = 16.5 V calculate the charge on the the 24.0 μF capacitor.
    108 μF (correct)

    (c) If ΔVab = 16.5 V calculate the charge on the the 7.00 μF capacitor.
    84.0 μF (correct)

    (d) If ΔVab = 16.5 V calculate the charge on the the 2.00 μF capacitor.
    I got 24.0 but its not correct.

    (e) If ΔVab = 16.5 V calculate the charge on the the capacitor C, which equals 14.0 μF.
    Likewise here.

    Any help on parts d and e is appreciated.

    You should start by checking your calculations for part(a); I get a slightly different answer than you. If you show me your work, I can show you where you went wrong.
