THE ELECTRIC CHARGE ON CONDENSATE AND WATER DROPLETS

Abstract

It was found that dew produced artificially on a thin wire was electrified negatively when the water temperature of the reservoir for supplying water vapor was lower than about 80C and positively when the temperature was higher than about 85C. The electrification phenomena of the condensate were considered to be originated from the electric charge on individual water droplets, because it was observed that the droplets were electrified when they rose from the water surface of the reservoir, and the sign of charge on the individual droplets agreed well with that of the condensate.
