About reasons for emergence of high-frequency current pulsation in electric discharges with direct contact to the liquid electrolyte

Consideration is made to the experimentally investigated electrical discharges in atmospheric pressure between the liquid electrolyte and metal electrodes in various embodiments of the polarity for their connection to a power supply. Obtained and analyzed are the spectra of the current signals in the megahertz range of frequencies. It is revealed that emergence of high-frequency current pulsation is accompanied by phenomena of dispersion and erosion of the electrodes.
