Equivalent capacitance

  1. Nov 14, 2012 #1
    1. The problem statement, all variables and given/known data

    I'm trying to find the equivalent capacitance for a circuit, but I keep getting stuck.

    2. Relevant equations
    C(parallel)=C1+C2+...Cn
    C(series)={(1/C1)+(1/C2)+(1/C3)+...(1/Cn)}^-1


    3. The attempt at a solution
    See the first penciled attachment.

    I would start by solving everything that is in series with no junctions in between. That should clean it up a bit. If you still have trouble, post your drawing again after doing that.

    Which ones are in series with no junctions in between? I've posted the original circuit in one attachment, but another attachment has my attempt where I thought I solved everything in series.

    your penciled attempt work out to be 3μF, which is same as mine and i think it is correct.
