Robert millikan oil drop experiment explained

WebBetween 1909 and 1910 the American physicist Robert Millikan conducted a series of oil-drop experiments. By comparing applied electric force with changes in the motion of the oil drops, he was able to determine the electric charge on each drop. He found that all of the drops had charges that were simple multiples of a single number, the fundamental charge … WebThe specific charge of an electron is 1.6⋅10 ^-19. In 1909, the oil-drop experiment was conducted by Robert Millikan and Harvey Fletcher for the purpose of determining a single electron's specific charge. The experiment is also known today as Millikan's experiment. In Millikan's experiment, two horizontal metal plates were placed on top of ...
