Electrodes' resistances

  1. Mar 28, 2013 #1
    Where can I find a set of equations that describe mathematically the resistance of various types of electrodes (e.g. hemispherical, conic, etc)?

    Thank you in advance!

    Look up "spreading resistance." You'll find the hemisphere and disk are the most widely used (for semiconductor contacts, e.g.). I haven't seen other shapes.
