Phenomena accompanying transient low-voltage discharges in liquid dielectrics: II - Cathode phenomena at low currents

THIS is the second of a series of papers1 dealing with the phenomena accompanying discharges resulting from spark-over at low voltages between metallic electrodes in a liquid dielectric. These phenomena are of particular concern because of developments in the art of electric-spark machining2 in which the effects of such discharges are used in the shaping of materials.
