The electrical qualities of porcelain, with special reference to dielectric losses

The following research was undertaken to determine some of the electrical properties of porcelain, and their variations with respect to potential, temperature, and time. The electrical properties investigated in this paper are as follows:— A. Capacity Measurements. 1. The rate of charge of a porcelain condenser. 2. The charge of a porcelain condenser as a function of the potential. 3. The influence of sudden cyclical changes of potential on the charge of a porcelain condenser. 4. The dielectric constant of porcelain as a function of the temperature, and its value.
