Concentration and temperature dependence of viscosity in the critical mixing region of aniline-cyclohexane An equation relating the potential applied to and the current flowing in a liquid dielectric has been derived. The theoretical equation predicts that beyond a certain threshold potential the current is independent of the applied potential and is proportional to the number of ions produced per unit volume per unit time.Measurements of the number of ions produced in cyclohexane as a function of temperature and water concentration were made. It was found that in the pure state about 200 ions/cm 3 -sec were produced, while in the water saturated cyclohexane at 50°C about 1.6X10 6 ions per cm 3 per sec were produced. It was concluded that the conductance in the pure state was due to ionization by cosmic radiation.When the cyclohexane was saturated with water, a large increase in the conductivity was observed as the cyclohexane passed through the freezing point. This behavior corresponds to an increase in the dielectric constant as noted by Seyer and Barrow.
