In this paper, numerical method for determining the capacitance of a conducting oblate spheroidal shell has been established. An explicit finite difference technique for solving Laplace's equation in oblate spheroidal coordinates systems for an axially symmetric geometry has been developed. An ingenious strategy was created to overcome the singularity problems encountered in the oblate spheroids. Consequently, the finite difference results were used to compute the capacitance of the spheroidal shell in an easy to understand manner. This was achieved using the Dirichlet boundary conditions on the oblate spheroidal surfaces. The shell capacitance results obtained did fall in the same range with those obtained using analytical method.
