This delicate equilibrium provides the foundational equation from which the charge of the droplet can be calculated, linking mechanical measurements to electrical phenomena. Procedure and Measurement Technique Millikan's procedure involved spraying a fine mist of oil into a chamber situated between the charged plates, allowing droplets to fall through a small hole.

After recording this terminal velocity, an electric field was activated to halt the droplet's descent, and the necessary voltage to achieve this suspension was precisely measured. The experiment's legacy is enduring, serving as a cornerstone for understanding atomic structure and electromagnetic interactions.
The consistent smallest value identified through this statistical analysis became the elementary charge, e. It allowed for the precise determination of Avogadro's number by correlating the macroscopic measurements of charge with the microscopic reality of electrons.

This discovery provided crucial validation for the emerging atomic theory and played a pivotal role in the development of quantum mechanics. This pattern of discrete jumps in charge, rather than a continuous spectrum, provided irrefutable evidence for the atomic nature of electricity.
