Apr 11, 2024 · In 1906, Robert Millikan determined that the electrons had a Coulomb (C) charge of -1.6 * 10 −19, something that allowed calculation of its mass as tiny, equal to 9.109 * 10 −31 kg. In the same time, experiments by Eugene Goldstein in 1886 with cathode discharge tubes allowed him to establish that the positive charges had a mass of 1.6726 ...
Robert Andrews Millikan was born on March 22, 1868, in Morrison, Illinois. He graduated from Oberlin College in Ohio in 1891 and obtained a doctorate at Columbia University in New York in 1895. In 1896 he became an assistant at the University of Chicago in Illinois, where he became a full professor in 1910. In 1909 Millikan began a series of ...
The American scientist Robert Millikan (1868–1953) carried out a series of experiments using electrically charged oil droplets, which allowed him to calculate the charge on a single electron. Millikan created microscopic oil droplets, which could be electrically charged by friction as they formed or by using X-rays.

Oil Drop Experiment. Millikan carried out a series of experiments between 1908 and 1917 that allowed him to determine the charge of a single electron, famously known as the oil drop experiment. Millikan sprayed tiny drops of oil into a chamber. In his first experiment, he simply measured how fast the drops fell under the force of gravity.
