Why was Millikan discovery important?

Millikan’s experiment is important because it established the charge on an electron. Millikan used a very simple a very simple apparatus in which he balanced the actions of gravitational, electric, and (air) drag forces.Click to see full answer. Hereof, why was Robert Millikan’s discovery important?Millikan received the Nobel Prize in 1923 in recognition of two major achievements: measuring the charge of the electron in his famous oil-drop experiment (see “This Month in Physics History,” APS News, August/September 2006), and verifying Einstein’s prediction of the relationship between light frequency and electronAlso, what did Robert A Millikan discover? Elementary charge Magnitude Also asked, how did Millikan contribute to the atom? Robert Millikan was an American, Nobel Prize-winning physicist, credited with the discovering the value for electron charge, e, through the famous oil drop experiment, as well as achievements related to the photoelectric effect and cosmic radiation.When did Robert Millikan contribute to the atomic theory?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.
