Question

Quizplus · Accepted Answer

The Millikan oil-drop experiment demonstrated that the electronic charge is quantized, meaning that it exists in discrete units rather than being continuous. This was shown by observing the behavior of oil droplets suspended in an electric field, and carefully measuring the forces acting on them. The results provided the first accurate determination of the fundamental charge of an electron.
