Abstract

A method and a device for producing an electric discharge between two electrodes are described. The method is characterized in that the electric arc resistance is substantially reduced at least between the electrodes to a resistance value which is close to or even lower than the critical resistance. This is achieved by placing between the electrodes an electrically conductive liquid medium (32) held in a substantially sealed container (30) surrounding the electrodes, whereby the electrical discharge rate between two electrodes can be improved while completely or substantially completely eliminating the latency time.
