Web2 dec. 2024 · During the 1890s, Millikan’s oil drop experiment was an important step toward fully embracing the electron theory. Millikan’s precise determination of the charge of an electron was a major factor in the development of atomic theory. As a result of his experiment, the principles of classical physics were established. WebMillikan oil-drop experiment, first direct and compelling measurement of the electric charge of a single electron. It was performed originally in 1909 by the American physicist Robert A. Millikan, who devised a straightforward method of measuring the minute electric charge that is present on many of the droplets in an oil mist.
