✦ Synopsis

A theoretical analysis is presented of the lumped capacitance method and its small capacitance approximation using a Debye dielectric permittivity relation and low frequency conductivity.

The influence of fringing fields are discussed. The results of the small capacitance method are compared with those for the thin cell method.
