Repeated measurements across numerous droplets to identify the common factor. They observed that the charge was always a multiple of a smallest, fundamental value, providing direct evidence for quantization.
Understanding Experimental Accuracy in the History of the Electron Charge
These droplets fell through a small hole under gravity, and their terminal velocity was measured using a microscope. By applying a voltage across the plates, the droplets could be made to rise, fall, or remain stationary.
Legacy and Impact on Modern Physics Millikan's oil drop experiment earned him the Nobel Prize in Physics in 1237, though the award ceremony referenced work from 1923. The mass of the droplet was derived from its measured terminal velocity during free fall, which depended on its radius and the viscosity of the air.

Results and the Discovery of Quantization The meticulous data collection yielded a value of approximately 1. The key was to balance the downward gravitational force with the upward electric force, allowing for the calculation of the charge on a single droplet.
