Abstract

A new type viscosimeter is described which enables the viscosity of any liquid to be measured while it is in an electric field. The electric field was found to increase the viscosity of all liquids with dipole moments, while the liquids without moments in general showed no effect. It was found that the change in viscosity varies with the shearing stresses to which the liquid is subjected. A qualitative theory is proposed which agrees very well with the results found experimentally.
