The problem of the spherical condenser

Abstract

Methods are given of computing to any desired accuracy the capacity of a spherical condenser when the bounding spherical surfaces are not concentric. Methods of calculating the attraction on the inner sphere and the maximum potential gradient in the field between the two shells are given. The results obtained are of use in calculating the capacity coefficients of spherical electrodes. They are directly useful also when measuring by standard methods the inductivity (specific inductive capacity), the thermal conductivity and the electrical conductivity of homogeneous substances.
