Integrating magnetic field

  1. Oct 14, 2011 #1
    1. The problem statement, all variables and given/known data
    There is a current of 20 A in a resistor that is connected in series with a parallel-plate capacitor. The plates of the capacitor have an area of 0.80 m2, and no dielectric exists between the plates. Find the value of the line integral B ∙ dl , where the integration path C is a 15-cm-radius circle that lies in a plane that is parallel with the plates and is completely within the region
    between them.


    2. Relevant equations
    b = muI/2rPI,


    3. The attempt at a solution

    i changed dl to 2PIdr and integrated. ended up with something that included ln(0). it just seemed wrong. any help is appreciated :)
