Viscosity dependence of dielectric liquids on electric field

Data on the dependence of the viscosity of liquid dielectrics (castor oil, petroleum oil, PMS-1, 5, CCl₄, and transformer oil) on applied voltage are considered. The experimental technique used is characterized by the absence of current passage through the liquid, as one of the electrodes was isolated from it. For castor and petroleum oils, viscosity decrease with increasing electric field is observed. For the other liquids the viscosity increases with increasing voltage. The material of the active electrode greatly influenced the results
