![]() It was in this experiment, known as the oil drop experiment, that he gained a great deal of fame. Robert Millikan has played a critical role in our understanding of physics. Millikan’s discovery of the same charge carrying capacity for electrons also helped. What is Millikan Atomic Theory? Robert Millikan was the first to discover the charge of an individual electron in 1910. The electron had previously been discovered to have a charge-to-mass ratio, according to J. Where did Millikan make his discovery? Millikan began measuring the charge on an electron with an oil drop as a professor at the University of Chicago in 1908. He began by measuring the distance between charged water droplets in an electric field. Who was Ra Millikan and when did he discover? Millikan began a series of experiments in 1909 in an attempt to determine how an electron carries an electric charge. Robert Millikan, using his own knowledge of physics, was the first to find the magnitude of the electron’s charge in 1910. What did Ra Millikan discover? Electricity’s transmission began to gain popularity in the 1890s with the acceptance of the theory that a tiny unit, the electron, carried it. The Discovery Of The Electron’s Charge By Robert Millikan. As a result of his work, Millikan conducted a famous oil-drop experiment, in which he discovered that an electron’s charge is always exactly the same as the charge of an oil drop. ![]() He used an electric field to measure the rate at which charged water droplets moved. Millikan began a series of experiments in 1909 to see how an electron carries an electric charge. Robert Millikan discovered the elementary charge of an electron during a physics experiment in oil droplets. He has had a significant impact on physics, and his discoveries have had a significant impact on current physics. Millikan’s research revealed that matter is made up of tiny particles, and that these particles are subject to physics laws. Millikan’s findings were an important contribution to understanding the fundamental nature of matter, and his work has had a lasting impact. Millikan’s famous oil- drop experiment was based on this work and investigated the electric charge of an electron, proving that it is always the same as the charge of a single oildrop. He found that this charge was always a multiple of the unit charge e. By measuring the force on the drop, he could calculate the charge on the drop. ![]() The oil drop was attracted to and stopped by a charged metal plate. His method was to use an oil drop, which he produced by allowing electric sparks in the presence of air to ionize the oil vapor. In 1909, Millikan began a series of experiments to determine the charge of the electron.
