What is the significance of Millikan's oil drop experiment?
Millikan found the charge of an electron- or pretty close to the accepted value
Who measured the charge on the electron?
Sir Joseph Thomson (J.J. Thomson) determined the charge of the electron in 1897, calling them "corpuscles." Previously electron beams had been referred to as Lenard rays and cathode rays.J.J. Thompson with his cathod ray tube experiment.
How does an electron become charged?
It doesn't really "become" charged. An electron is always charged, and it can only have a charge of -e where value of elementary charge e is 1.602 * 10-19 C as found first by Millikan with his famous oil drop experiment
Who discovered the charge to mass ratio for the electrons?
Millikan found the charge of an electron by his famous oil drop experiment. J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass. With these two values one can find the mass of electron by dividing the charge value by its specific charge.
Which experiment Faraday did about clue of electron?
That experiment's name was "electrolysis"
What experiment did Millikan do?
Robert Millikan was the first to measure the electrical charge of an electron.
What is the significance of Millikan's oil drop experiment?
Millikan found the charge of an electron- or pretty close to the accepted value
A physicist who determined the chare of an electron by means of his oil-drop experiment?
There are two scientist working together: The oil drop experiment was an experiment performed by Robert Millikan and Harvey Fletcher in 1909 to measure the charge of the electron (the elementary electric charge).
What oil drop experiment allowed Millikan to measure the?
The charge of the electron
Who calculated the negative charge of an electron?
The brilliant, so-called "Oil-drop experiment" of Robert A. Millikan established the magnitude of the quantum of electric charge ... the amount of charge on each electron (negative) and each proton (positive). Search around on line for "Millikan oil drop experiment" to read the fascinating story of how it was done.
Who discovered change of electron by oil droplet experiment?
Robert Andrews Millikan
Millikan's oil drop experiment helped determine the mass of an electron by allowing scientists to measure which of these?
the charge carried by an electron A+
How did Millikans experiment change your view on atoms?
Millikan measured the first the electrical charge of an electron.
Who measured the charge on the electron?
Sir Joseph Thomson (J.J. Thomson) determined the charge of the electron in 1897, calling them "corpuscles." Previously electron beams had been referred to as Lenard rays and cathode rays.J.J. Thompson with his cathod ray tube experiment.
Which scientist furthered knowledge of the electron by determining its charge and mass using an oil-drop experiment in 1909?
Robert Millikan
Why electron has negatively charged?
The determination of charge of an electron was done by R.A. Millikan in 1913, In R.A. Millikan's working (Millikan's oil drop experiment) explained as follows the terminal velocity of charged oil drop is measured under two conditions viz. under gravity alone and under the combined action of gravity and electric field oppose the gravity . Negatively charge drop is selected and its motion is studied.I think it's due to this electron has (-)ve charge.In fact, it is a very long experiment ,i can't explain all of it.
What was Robert Millikan's theory?
Robert Millikan measured the electrical charge of the electron.
