The Millikan Oil-Drop Experiment

Robert Millikan measured e, the magnitude of the elementary charge on an electron, and demonstrated the quantized nature of this charge with the help of a brilliant set of experiments from 1909 to 1913. The experiment is known as The Millikan Oil-Drop Experiment. His apparatus, diagrammed in Figure 1, contains two parallel metallic plates. Oil […]
