Electrical conduction in purified polar liquids

The increase of the initial conductivity of highly pure water, taken as a type of polar liquid, with applied electric field is in complete agreement at every field and up to breakdown (10 6 v cm -1 ) with the theory given by Plumley but disagrees with the Onsager theory. Electrical losses measured at 50 c/s, in pure ethanol, submitted to a strong agitation by means of fast rotating cylindrical electrodes in order to prevent excessive polarization, lead to the same conclusion.
