DESCRIPTION
The density of charge on a spherical conducting surface is uniform, while the density of charge increases with the curvature of convex points on a conducting surface. In fact, conductors with points tend to discharge rapidly when charged because the electric field due to charges is strongest where the curvature is greatest. A point may be considered the limit of least radius of curvature and thus the strongest possible diffuser of charge. Exhibit 16 is a single point on a brass base intended to demonstrate the charge loss at a sharp point.BIBLIOGRAPHY
