  1. Millikan oil-drop experiment

    Millikan's original experiment or any modified version, such as the following, is called the oil-drop experiment. A closed chamber with transparent sides is fitted with two parallel metal plates, which acquire a positive or negative charge when an electric current is applied. At the start of the experiment, an atomizer sprays a fine mist of oil droplets into the upper portion of the chamber.

  2. Oil drop experiment

    Oil drop experiment. 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. [3] [4] [5] Millikan received the Nobel Prize in Physics in 1923.

  3. Millikens Oil Drop Experiment

    Milliken's Oil Drop Experiment Calculation. F up = F down. F up = Q . F down = m.g. Q is an electron's charge, E is the electric field, m is the droplet's mass, and g is gravity. One can see how an electron charge is measured by Millikan. Millikan found that all drops had charges that were 1.6x 10 -19 C multiples.

  4. The Millikan Oil Drop Chemistry Experiment

    The Millikan Oil Drop Experiment. 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 ...

  5. Millikan's Oil Drop Experiment: How to Determine the Charge of an

    Millikan's oil-drop experiment was performed by Robert Millikan and Harvey Fletcher in 1909. It determined a precise value for the electric charge of the electron, e. The electron's charge is the fundamental unit of electric charge because all electric charges are made up of groups (or the absence of groups) of electrons.

  6. Millikan oil drop experiment

    In Millikan's experiments ρ oil was 919.9 kg m -3 and ρ air was 1.2 kg m -3. The precision of the density of air is much less vital than that of the oil. The gravitational field g varies geographically, partly because of fluctuations in the earth's density and partly because of the eath's rotation. In Chicago g = 9.803 kg s -2.

  7. The Millikan Oil Drop Experiment

    The Experiment. 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. These metal plates obtain a negative ...

  8. 4.12: Oil Drop Experiment

    The oil drops picked up static charge and were suspended between two charged plates. Millikan was able to observe the motion of the oil drops with a microscope and found that the drops lined up in a specific way between the plates, based on the number of electric charges they had acquired. Figure 4.12.2 4.12. 2: Oil Drop experiment.

  9. Millikan's Oil Drop Experiment

    Oil Drop Experiment Free Body Diagram. Now after turning on the electric field between the plates, the electric force F E acting on the drop is, Where E is the electric field and q the charge on the oil drop. For parallel plates, the formula for E is, Here V is the potential difference and d the distance between the plates. That implies,

  10. PDF The Millikan Oil-Drop Experiment

    This experiment first described in 1913, is based on the fact that different forces act on an electrically charged oil drop moving in the homogeneous electric field of a plate capacitor (Figure 1). Going through the capillary of the atomizer, the oil droplets acquire electric charge due to friction. The effect is known as triboelectric charging.

  12. Oil Drop Experiment

    The oil drop experiment is an experiment that allows a precise meaurement of the elementary charge e e. The experiment was developed and performed in 1910 by the american physicist Robert Andrews Millikan. He measured the following value for the elementary charge: e =1.592 ⋅10−19C e = 1.592 ⋅ 10 − 19 C. Nowadays there are more precise ...

  13. Millikan's Oil Drop Experiment

    Millikan suspended oil droplets between two electric plates and determined their charges. Oil droplets from a fine mist fell through a hole in the upper floor. From their terminal velocity, he could calculate the mass of each drop. Millikan then used x-rays to ionize the air in the chamber. Electrons attached themselves to the oil drops.

  14. August, 1913: Robert Millikan Reports His Oil Drop Results

    Robert Millikan. Robert Millikan's famous oil drop experiment, reported in August 1913, elegantly measured the fundamental unit of electric charge. The experiment, a great improvement over previous attempts to measure the charge of an electron, has been called one of the most beautiful in physics history, but is also the source of allegations ...

  15. Millikan Oil Drop Experiment

    Millikan Oil Drop Experiment. This is the original equipment used by Robert Millikan and Harvey Fletcher in 1909 at the Univeristy of Chicago to measure the electric charge on a single electron. With incredible perserverence, they were able to determine the charge to within 1% of the currently accepted value.

  16. The Millikan experiment

    Millikan repeated the experiment for over 150 oil drops. He selected 58 of his results and found the highest common factor. That is, the single unit of charge which could be multiplied up to give the charge he measured on all his oil drops. The calculations. 1 When the oil drop is in the electric field, there is an electric force, F, acting ...

  17. Millikan's Oil Drop Experiment

    Millikan's experiment was meant to have the drops fall at a constant rate. At this constant rate, the force of gravity on the drop and the force of the electric field on the drop are equal: F up = F down. Q is the charge of an electron, E is the electric field, m is mass of the droplet, and g is gravity.

  18. Millikan's oil drop experiment to determine charge of an electron

    This chemistry video for Grade 10-11 students demonstrates R. A. Millikan's oil drop experiment to calculate the charge of an electron.

  19. The Oil Drop Experiment

    The Millikan Oil Drop Experiment. ... What Millikan did was to put a charge on a tiny drop of oil, and measure how strong an applied electric field had to be in order to stop the oil drop from falling. Since he was able to work out the mass of the oil drop, and he could calculate the force of gravity on one drop, he could then determine the ...

  20. The Millikan Oil-Drop Experiment

    Description. This simulation is a simplified version of an experiment done by Robert Milliken in the early 1900s. Hoping to learn more about charge, Milliken sprayed slightly ionized oil droplets into an electric field and made observations of the droplets. When the voltage is zero and the run button is pressed, the drop will fall due to the ...

  21. How Did People Find the Fundamental Charge With Drops of Oil?

    So, you could have an oil drop with a charge of 1e, 2e, or 3e, but not 1.5e (where e = 1.6 x 10 -19 C). Thus, Millikan was able to measure this fundamental charge value. His value was 1.592 x 10 ...

  22. Electron charge from Millikan's oil drop experiment

    Millikan watched the droplets for prolonged period of time, where he would zap the droplets by X-ray, and keep experimenting on it till it lost all charge, then zap it again randomly. And he observed MANY such drops. The drops always lost charges in simple whole number ratios.
