AbstractRaindrops were admitted by a cone‐shaped opening into an insulated vessel connected to a valve amplifier for measuring the drop chargeQ.Drop radius a was found by the absorbent paper method. The field at the ground and the point discharge currentIwere also measured. Most often, but not always, the signs of the drop charge and field were opposite. During point discharge, 173 drop charges and masses were measured, and statistical analysis showed a definite correlation betweenQandI—, a probable correlation betweenQ/—I andaand a possible correlation betweenaand —Q. By grouping drops according to radius, and taking averages within the groups, the approximate relationshipQ/—I ∞ a was obtained. In one period when the radius was nearly constant, the observations gave the connectionQ∞ —Iwithout taking averages. The observed relation betweenQandIcorresponds to the results of Simpson (1949) for the charge on a volume of rain. The observed charges were mostly much higher than predicted on Wilson's ion‐capture theory, unless the field increases considerably with height
