Abstract

We used a combined approach, investigating capacitance, resistance, and electrooptic reply of nematic liquid crystals within the same experimental framework, which enabled us to plot the phase delay as a function of electric parameters. Phase delay vs. capacitance curves are almost linear, but the slope is frequency dependent for the liquid crystal with the low-frequency dispersion of the dielectric anisotropy. To interpret the results, equivalent electric parameters definition, consistent with the AC current measurement techniques, is presented and phenomenological theory of the RC-parameters is developed. When completed by the Ericksen-Leslie equation for the liquid crystal molecules realignment in the external electric field, the theory is in good agreement with the experiment.
