Detailed explanation-1: -Millikan determined the charge of the electron to be 4.77 ± 0.009×10−10 electrostatic units (1.592×10−19 coulombs).
Detailed explanation-2: -His earliest major success was the accurate determination of the charge carried by an electron, using the elegant “falling-drop method”; he also proved that this quantity was a constant for all electrons (1910), thus demonstrating the atomic structure of electricity.
Detailed explanation-3: -Millikan’s Oil Drop Experiment: Measuring the Charge of the Electron. 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.
Detailed explanation-4: -March 22, 1868-December 19, 1953 Robert Millikan was a physicist who discovered the elementary charge of an electron using the oil-drop experiment.
