✦ Synopsis

It is well known that the discharge of an electrically charged hydrocarbon liquid need not follow an exponential law. The present paper shows that this process can still be correctly described mathematically with the aid of Ohm's Law.

Recently a new theory for static relaxation has been put forward. It has been claimed that this "hyperbolic theory" better describes relaxation of charge from high resistivity fuels than is possible with the "ohmic theory", by which is meant a theory based on the assumption of constant conductivity.

However, Ohm's Law does not require that the conductivity shall be constant. It is shown in the present paper that the hyperbolic theory is a special case of a more general treatment. Furthermore it is shown that by taking association and dissociation effects into account it is possible to describe certain types of relaxation curves which cannot be described by either the hyperbolic theory or the constant conductivity theory.
