A liquid drop from a capillary, when it is electrified, can take different forms in association, with the amount of electrification. This behavior was studied for 36 kinds of liquids. For the, liquids with electrical conductivity above 10-12 (ohm•cm)-1, the drops tended to be disintegrated and to become mists with increasing an applied voltage. In this case, the disintegration was found. to be strongly affected by the surface charge density of drops. For the liquids with conductivity below 10-12 (ohm•cm)-1, however, the increase of applied voltage only resulted in the increase of the volume of drops, and no mist formation was observed. The results were interpreted as kind of prebreakdown phenomena accompanying mists between needle and plane electrodes.
