American Physicist, Robert Millikin in 1909
There are two scientist working together: The oil drop experiment was an experiment performed by Robert Millikan and Harvey Fletcher in 1909 to measure the charge of the electron (the elementary electric charge).
Dalton performed the cathode ray experiment.
Felix Ehrenhaft has written: 'The microcoulomb experiment; charges smaller than the electronic charge'
Millikan's oil-drop experiment demonstrated that charge is quantized, and that the quantum of charge ... the 'elementary' charge ... is 1.6 x 10-19 Coulomb.
Alpha has 2 positive electronic chargeBeta has 1 negative electronic charge. There is also positive beta that are having 1 positive electronic charge.Gamma has no electronic charge.
The test charge is positive in the experiment.
Robert Millikan is credited with the discovery of the elementary electronic charge through his oil drop experiment.
The maximum charge for the capacitor in this experiment is approximately 5.0 microcoulombs.
The unit of charge is coulombs

Robert Andrews Millikan won the Nobel Prize in Physics in 1923 for his measurement of the elementary electric charge, which he determined using his oil-drop experiment. This experiment demonstrated that electric charge is quantized, shedding light on the fundamental nature of electricity.
