Original Abstract
Electrical discharges in liquids can be generated in several electrode configurations; one of them is called as pin-hole. The discharge is created inside a small orifice connecting two chambers filled by any conductive solution. Each chamber contains one of the electrodes. Based on the orifice length/diameter ratio, the discharge is called as capillary or diaphragm. The presented contribution gives the preliminary detailed observation of the discharge creation in the dependence on the orifice shape for selected solution conductivities. The non-pulsing DC high voltage was used for the presented study. The bubble theory of the discharge generation was confirmed at the set conditions. However, the streamer like character was ocassionally observed after plasma ignition, too.
