Millikan's oil drop experiment stands as one of the most elegant and consequential investigations in the history of physics. Measured terminal velocity of a droplet under gravity.
Applying Voltage to Control and Measure Suspended Droplets
Its impact extends far beyond a single measurement; it provided the definitive proof of the electron's particulate nature and validated the emerging quantum theory. The hypothesis was that electric charge exists in specific, indivisible units, and confirming this quantization would provide a robust foundation for modern atomic theory.
They observed that the charge was always a multiple of a smallest, fundamental value, providing direct evidence for quantization. These droplets fell through a small hole under gravity, and their terminal velocity was measured using a microscope.

The experiment effectively pinned down the fundamental unit of electricity, a triumph of precision measurement. Today, the principles of balancing forces in this experiment remain a cornerstone conceptual tool in physics education and research.
