On the Electrification of Water Drops by Breaking due to the Electrostatic Induction under a Moderate Electric Field

[摘要] The charge on water droplets produced by the breaking of drops under an electric field of strength 20v/cm was measured by a cathode ray oscillograph; the charge was found to be larger than that due to Lenard's effect. From both experimental and theoretical considerations, it was concluded that the charge on the droplets resulted from electrostatic induction in such a manner that the surface charge induced on the surface of the drop under the field was left on the droplets after they were disrupted.
