A Fredholm integral equation of the first kind has been developed for finding the resistance of a circular conducting plate buried. in a homogeneous earth. The method of moments is used to solve the equations. An extremely fast rate of convergence has been gained by expanding the charge distribution in functions with an appropriate singularity. Contrary to popular perceptions, the grounding resistance is not inversely proportional to the area of the disk. An empirical formula for evaluating the resistance of a disk in terms of its radius, its depth of burial and the conductivity of the earth has been derived.
