The electrical conductivity and permittivity of mixtures, with special reference to emulsions of water in fuel oil

Abstract

The electrical characteristics of a mixture of two substances are dependent only in part on the electrical characteristics of the individual phases. In addition to the volume ratio of the components of the mixture other factors such as particle shape and distribution have important effects on the characteristics. In this connexion an emulsion formed of a liquid with a high conductivity in one of low conductivity is free from the complications of many practical mixtures. The droplets are spheres and the system approaches the case which has been attacked theoretically with the greatest success.
