Energy stored within a circuit

  1. Apr 9, 2012 #1
    1. The problem statement, all variables and given/known data
    In the figure (link below), C1 = 20 [itex]\mu[/itex]F, C2 = 24 [itex]\mu[/itex]F, C3 = 16 [itex]\mu[/itex]F, C4 = 20 [itex]\mu[/itex]F, C5 = 22 [itex]\mu[/itex]F, and V = 20 V. How much energy is stored by C2?

    Here's the figure:

    2. Relevant equations
    Q = C[itex]\Delta[/itex]V
    Ucap = (1/2)C[itex]\Delta[/itex]V2
    Ceq = C1 + C2 + C3 + ....

    3. The attempt at a solution
    This was a last problem on a test that I got destroyed on, and we're getting credit for corrections but I'm still clueless to where I start. Any help is appreciated!

    Some capacitors are connected in parallel, others in series. Determine the resultant of the capacitors C1, C2, C3, C4.
