Describe oil drop experiment
Oil drop experiment apparatus Millikan's and Fletcher's apparatus incorporated a parallel pair of horizontal metal plates. By applying a potential difference across the plates, a uniform electric field was created in the space between them. Summary The oil drop experiment allowed Millikan to determine the charge on the electron. He later used this data to determine the mass of the electron. 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.

Millikan's experiment is based around observing charged oil droplets in free Terminal velocity. As an object falls through a fluid, such as air
But using his famous Oil Drop Experiment, Millikan indirectly measured the charge This article describes an activity that allows students to recreate his clever
25 Jul 2019 The experiment was performed by spraying a mist of oil droplets into a chamber above the metal plates. The choice of oil was important because 19 Sep 2019 Einstein had essentially proposed that the accepted theory of light was wrong, and he had a new theory that could explain the photoelectric effect, Oil-drop experiment was the first direct and compelling measurement of the electric charge of a single electron. It was performed originally in 1909 by the The Millikens Oil Drop Experiment was an experiment performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the charge of an electron. 6 Jun 2005 Most freshman chemistry courses and texts describe the classic experiments that led to the development of atomic theory. Among the 1 Sep 2006 This work describes the use of refrigerator magnets and BB's as an analogy to Millikan's oil-drop experiment. The mass of a single BB is I vaguely remember doing a Millikan oil drop experiment in a lab in college, 60+ years ago. Here is an example. With enough measurements the statistical error
9 Jun 2005 The purpose of Robert Millikan's oil-drop experiment (1909) was to measure the electric charge of the electron. He did this by carefully
His experiment measured the force on tiny charged droplets of oil suspended against gravity between two metal electrodes. Knowing the electric field, the charge 14 Sep 2012 If you want to be fancy, you might also describe what further experiments may be needed to continue to explore the subject of the first experiment.
Can someone explain Robert Millikan's oil drop experiment to me? I have to do a project on it but I can't understand it at all. Can someone just briefly explain: A) What the experiment was. B) What happened in the experiment. C) What was the significance of the experiment (like what was proven, why was it important?)
The oil drop experiment was an experiment performed by Robert Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). The experiment entailed balancing the downward gravitational force with the upward buoyant and electric forces on tiny charged droplets of oil suspended between two metal electrodes. 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. The choice of oil was important because most oils would evaporate under the heat of the light source, causing the drop to change mass throughout the experiment.
This remains controversial since papers found after Fletcher's death describe events in which Millikan coerced Fletcher into relinquishing authorship as a condition
Best Answer: Yeah sure. The experiment was to find the charge (and the mass) of an electron. Previously, the charge-to-mass ratio of electrons was known (the charge divided by the mass). But in all previous experiments, there was no way to look at either charge or mass independently. Millikan oil-drop experimentBetween 1909 and 1910 the American physicist Robert Millikan conducted a series of oil-drop experiments. By comparing applied electric force with changes in the motion of the oil drops, he was able to determine the electric charge on each drop. Millikan used the oil-drop experiment to demonstrate the discreteness, or singleness of value, of the electronic charge, and to make the first accurate measurement of the value of this constant. In that experiment, a small charged drop of oil is observed in a closed chamber between two horizontal parallel plates.
