  1. Millikan oil-drop experiment

    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 straightforward method of measuring the minute electric charge that is present on many of the droplets in an oil mist. The force on any electric charge in an electric field is equal to ...

  3. 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. [ 6]

  4. Millikan's Oil Drop Experiment

    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. Oil Drop Experiment.

  6. 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. Millikan's Oil Drop Experiment

    The Oil Drop Experiment. In 1909, Robert Millikan and Harvey Fletcher conducted the oil drop experiment to determine the charge of an electron. They suspended tiny charged droplets of oil between two metal electrodes by balancing downward gravitational force with upward drag and electric forces. The density of the oil was known, so Millikan and ...

  9. PDF The Millikan Oil-Drop Experiment

    This experiment first described in 1913, is based on the fact that diferent 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 efect is known as triboelectric charging.

  10. 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.

  11. 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.

  14. PDF Millikan's Oil Drop Experiment

    In 1909, Robert Millikan and Harvey Fletcher developed an experiment to determine the fundamental charge of the electron. This was achieved by measuring the charge of oil drops in a known electric field. If all electrons have the same charge, then the measured charge on the oil drops must be multiples of the same fundamental constant.

  15. Physics

    Robert Millikan's oil drop experiment provided the first clear measurement of the fundamental electric charge and thus helped cement the notion that nature is "grainy" at the smallest level. The first results came out in 1910, but the seminal work was a 1913 paper in the Physical Review .

  17. Millikan's Oil Drop Experiment

    The experiment initially allows the oil drops to fall between the plates in the absence of the electric field. They accelerate first due to gravity, but gradually the oil droplets slow down because of air resistance. The Millikan oil drop experiment formula can be given as below. Fup = Q ⋅ E Fdown = m. Where Q is an electron's charge, m is ...

  19. Millikan's Oil Drop Experiment

    Robert Millikan utilised Newtonian physics and small oil droplets to determine the charge of an electron - a feat that Thomson could not previously achieve. Millikan used an atomiser to spray droplets of oil into a chamber in which the oil droplets eventually would fall into a strong electric field. Within this field (between charged metal ...
