Calculate copper plate resistance

  1. May 6, 2007 #1
    If I have a sheet of copper, how can i calculate its resistance? do i just take the surface area of the thin side and compare it on an AWG chart?

    It depends in which axis you want to do the calculation, but in all cases you would just use the resistivity formula:

    [tex]R = \frac{\rho L}{A} [/tex]

    Where [tex]\rho [/tex] is the resistivity in Ohm*meters
