The Millikan Oil Drop experiment consisted of a mist of oil droplets being sprayed in to a chamber containing both a positive and negatively charged brass plate. The oil droplets fall though a small hole in the top plate and are charged with electrons by the means of X-Rays. The plates create an adjustable electric field by varying the voltage, repelling the charged oil droplet against the forces of gravity. When the electrical force and gravitational force were balanced, establishing a mechanical equilibrium, the oil droplet would have suspended in mid-air. All of this is observed from a microscope appended to the chamber.
