Notation of permittivity in farads per meter question

  1. Jan 19, 2013 #1
    I am using an old textbook as a reference, and the equation given for the electrical permittivity of free space ε0 is given in terms of:


    (Fm-1)

    where this measurement notation represents farads per meter. Why the superscript of -1 in the notation?

    x^(-1) = 1/x

    Fm(-1) = F/m

    Are you sure you didn't already know that?

    Oh, geesh. Duh. Yeah, I knew that. Thanks!
