Abstract: The sizes of raindrops with radii between 0.025 and 0.2 cm can be measured by amplifying the voltage pulses they make when they hit a high voltage wire. I have made such a device using two wires charged to +2000 V and a ...

Abstract: A very abrupt rise in capacity occurs as a water drop approaches and comes in contact with one of the electrodes of a capacitor. This capacity change can be used to measure drop sizes and thus to determine dropsize ...
