Millikan's oil-drop experiment was performed by Robert Millikan and Harvey Fletcher in 1909. It determined a precise value for the electric charge of the electron, e. The electron's charge is the fundamental unit of electric charge, because all electric charges are made up of groups (or the absence of groups) of electrons. Conclusions. Millikan's oil drop experiment has showed that the electric charge in oil drops is quantized, and has allowed a determination of its value to . The experiment has neither proved that the value of the fundamental electric unit is on the order of nor that electric charge in itself is quantized.
Robert Millikan's oil drop experiment measured the charge of the electron. The experiment was performed by spraying a mist of oil droplets into a chamber above the metal plates.

Ignoring the Cunningham correction factor , the charge of an oil drop is obtained from the formula: (1) with the viscosity of air, the radius of the oil drop, the electric eld strenght, the terminal velocity of the drop in the presence of an electric eld and the (terminal) velocity of the drop in the absense of the electric eld. Remember that
