Robert Millikan, American physicist honored with the Nobel Prize for Physics in 1923 for his study of the elementary electronic charge and the photoelectric effect. He is also known for his famous oil-drop experiment that led to his Nobel-winning discoveries.
During the 1890s the theory that electricity was conveyed by a miniscule unit, the electron, gained acceptance. In 1910 Robert Millikan succeeded in precisely determining the magnitude of the electron’s charge.
Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American physicist who won the Nobel Prize in Physics in 1923 for the measurement of the elementary electric charge and for his work on the photoelectric effect.
How did Robert Millikan change the atomic model? Prior to Robert Millikan's famous oil drop experiment, in which he measured the charge on a single electron, it was not known if...
Millikan 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 method of measuring the minute electric charge that is present on many of the droplets in an oil mist.
The Oil Drop Experiment was performed by the American physicist Robert A Millikan in 1909 to measure the electric charge carried by an electron. Their original experiment, or any modifications thereof to reach the same goal, are termed as oil drop experiments, in general.
Robert Millikan’s oil drop experiment provided the first clear measurement of the fundamental electric charge and thus helped cement the notion that nature is “grainy” at the smallest level. The first results came out in 1910, but the seminal work was a 1913 paper in the Physical Review.
