Numerical Computation of Capacitance of Oblate Spheroidal Conducting Shells

A spheroid is obtained by rotating an ellipse about one of its principal axes. If the ellipse is rotated about its major axis, a prolate spheroid is formed, while an oblate spheroid is formed if the ellipse is rotated about its minor axis. However, if the generating ellipse is a circle, a sphere is formed. Spheroidal coordinates eliminate the cumbersome mathematical …
