Capacitance from a separated plate disk

  1. Apr 9, 2009 #1
    1. The problem statement, all variables and given/known data

    Ok, lets say that I have two plate disk, with an area of A and they are separated with a distance d apart from each other. I need to measure the half-life of exponential decay to calculate capacitance. I need to graph C vs x = 1/d, however how can I get C ??


    2. Relevant equations



    3. The attempt at a solution

    kindly be a bit clear. what is x here. we have a formula of C = e0A/d for capacitance in the form of parallel plate. is it working???

    x = 1/d .... yes, C = e0A/d works.. what does the half-life of exponential decay means?
