  • Abstract
    Study of the structure of electrohydrodynamic currents shows that carriers of an electrical charge (ions) are practically “frozen” in an environmental liquid. In other words, ions in low-conducting liquids are capable of forming more or less steady structures. One method of study of this effect is ultrasound velocity dispersion on charged supermolecular formations. Results of both theoretical and experimental research on acoustic dispersion in liquid dielectrics under the influence of pre-breakdown electrical fields are presented. It is shown that the dependence of sound velocity on frequency has resonant character. The resonant frequency is determined by the density of electrical charge and mass of the charged supermolecular structures
