The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). [ 1 ] [ 2 ] The experiment took place in the Ryerson Physical Laboratory at the University of Chicago .
Millikan oil-drop experiment, first direct and compelling measurement of the electric charge of a single electron. It was performed originally in 1909 by the American physicist Robert A. Millikan, who devised a method of measuring the minute electric charge that is present on many of the droplets in an oil mist.
2 lut 2023 · The Oil Drop Experiment was performed by the American physicist Robert A Millikan in 1909 to measure the electric charge carried by an electron. Their original experiment, or any modifications thereof to reach the same goal, are termed as oil drop experiments, in general.
In an important series of experiments in Chicago, Robert Millikan measured the charge on a series of oil drops. He did this by observing the time taken for a drop to fall at its terminal velocity under the influence of gravity between two fixed levels, this enabled him to deduce the radius of the drop and therefore the drag force operating on it.
Devised by Robert A. Millikan and Harvey Fletcher, the Millikan Oil Drop Experiment is conducted in a chamber and is a method of measuring the electric charge of a single electron. To elaborate, this chamber contains an atomizer, a microscope, a light source, and two parallel metal plates.
Most science educators would consider J.J. Thomson’s cathode rays, E. Rutherford’s al-pha particles, and R.A. Millikan’s oil drop experiments to be three of the most important con-tributions to our understanding of modern chemistry and physics.
A description of the historic oil drop experiment that was performed by Robert Millikan to determine the electrical charge of the electron. Included is a diagram of the apparatus used and a discussion of the forces acting on the oil droplets.
