In 1911, Robert A. Millikan, with his famous "oil drop" experiment, not only discovered
that charge always occurs in multiples of the same elementary quantity, but also
measured the size of that quantity. This, along with his painstaking measurements
on the photoelectric effect, won him the 1923 Nobel Prize in Physics.

What is a unit of measuring rate of electron flow in a circuit called?
Electron flow is known as 'current' the unit of current is an amp
How do we measure electrical current and electrical charge?
The definition of Electric Current in my books when I was learning is - the time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time. The definition of Electric Charge is - one of the basic properties of particles of matter enabling all electric and magnetic forces interactions, there are 2 kinds of charge Positive and Negative.Electric charge is measured by coulombs (coulomb is 1 ampere per second) and electric current is measured by amperes. If trying to measure use a ammeter.
What determines the time of a given location on earth?
The time of a given location on Earth is determined by its position within a time zone. Time zones are based on longitudinal lines and are typically one hour apart. The time is also influenced by whether the location observes daylight saving time.
How is sea level determined and what factors are taken into consideration in the process?
Sea level is determined by measuring the average height of the ocean's surface over a specific period of time. Factors such as tides, winds, currents, and temperature variations are taken into consideration in this process.
Why is the formula for magnesium oxide Mg3O2?
Nitrogen is in group 5A of the periodic table and needs 3e to complete the octet rule, Mg is in group 2A of the periodic table and can only give out 2e to complete the octet rule, hence the formula Mg3N2
The understanding that the position of an electron in an electron cloud cannot precisely be determined was developed by Werner Heisenberg and is known as the?
"Uncertainty Principle". He didn't say that the position can't be precisely determined. He said that the position and the momentum can't both be precisely determined at the same time. The more precisely you determine one, the more fuzzy the other becomes at the same time.
What is the jail time for theft charge of 146 or a felony charge of 186 stealing from khols in Illinois?
It is probably determined by the amount of the theft.
How big is a proton compared to an electron?
A proton is about 1,836 times heavier than an electron. In terms of size, the proton is also larger than an electron. However, the exact size of both particles is extremely small, with the proton being about 100,000 times smaller than an atom.
What are laws and sentencing for a first time charge of child molestion?
It depends on the charge and the conviction record of the convicted person. Then it is determined by the sentencing guidelines of the state in which the case is tried.
What kind of electrical charge is found on the oxygen atom of a polar molecule?
A slight negative charge as the electron(s) shared in the covalent bond are spending more time in the highly electronegative oxygen orbital.
What are the electron charge packs for on fallout 3?
Electron charge packs are ammunition used in energy weapons such as the laser pistol, laser rifle, and plasma rifle in Fallout 3. They are consumed each time you fire these weapons, so you need to find or purchase more to keep using them.
Why don't nucleus revolve around electron?
The nucleus and the electron both revolve around a common center of charge. The only atom with equal charge in both places is hydrogen. Every atom heavier than hydrogen has more charge in the nucleus than there is on an electron. By the time you get to uranium, there is more than 90 times as much charge in the nucleus as there is on an electron, so the common center of charge is many times farther from each electron than it is from the nucleus. Also, each nuclear particle ... each proton and neutron ... is almost 2000 times more massive than an electron, and the same argument applies to the center of mass in the case of orbits governed by gravitational force, such as the solar system. But in the atom, the electrical forces completely dominate over the gravitational forces (by something like 1040.)
What did Robert Millikan discover about the electron?
Born in Morrison, Illinois, Robert Andrew Millikan was the second son of the Reverend Silas Franklin Millikan and Mary Jane Andrews. When Millikan was seven, his family moved to Maquoketa, Iowa, where he attended high school. In 1886 he entered Oberlin College in Ohio. In 1887 he enrolled in several classics classes there, and because he did quite well in Greek, at the end of his sophomore year, he was asked to teach an introductory-level physics class. He enjoyed teaching physics and accepted a two-year teaching post at Oberlin upon graduation in 1891. It was during this period that he developed an even keener interest in physics.In 1893 Millikan began his doctoral work at Columbia University, receiving a Ph.D. in 1895. After travelling to Germany, he eventually accepted a faculty position at the University of Chicago. It was as a teacher and textbook author that Millikan first made his mark. He wrote or co-wrote a number of elementary physics texts that became the classics in this field. However, while valued activities, they did not lead to his promotion to full professor. Determined to ascend in academic rank, Millikan began his research into the charge on the electron.At the time, the debate over whether or not atoms were real had almost played out, but the questions surrounding the true nature of the electron were still unanswered. Although the work of the English physicist J. J. Thomson had elucidated the charge-to-mass ratio, determining that the electron had a discrete, fixed charge and mass remained.Being an experimentalist, Millikan used a tiny, submillimeter drop of oil suspended between capacitor plates to measure the incremental charge on an electron. His reasoned that the oil drop would pick up a charge due to friction as it entered the region between the plates. By ionizing the atmosphere and monitoring the motion of multiple drops, he was able to compare the time that the drop took to fall under the influence of gravity and with the electrical plates off, against the time that it took for the drop to climb under the influence of applied voltage . The interaction of the drop with the electric field always occurred in discrete units, indicating that the electron charge was a single value, and that it was the same value for all different forms of electricity.Millikan's oil-drop experiment settled the argument and determined accurately (within one part in a thousand) both the charge and, by virtue of the charge-to-mass ratio, the mass of the electron. Both numbers allowed the Danish physicist Niels Bohr to finally calculate Rydberg's constant and provided the first and most important proof of the new atomic theory .Millikan went on to demonstrate the photoelectron effect, providing a valuable proof of Albert Einstein's equations. His experiments also aided both Einstein and Bohr in their later research efforts. In 1923 he was awarded a Nobel Prize in physics for both his work in determining the charge on the electron and exploring the photoelectric effect.
What is current and its unit?
current is the amount of electron charge passing a point in a conductor per unit of time.Its unit is ampere
Where is the location of an electron in an electron cloud?
This great question is one of the questions in physics that led to quantum mechanics. It turns out that the electron's location cannot be determined with precision. It can only be assigned a probablity associated with it being in a given location at a given time. Furthermore, it is a mistake to think that this is because it is just difficult to do. The electron's position truly is only a probability not matter how carefully you try to measure it.
How long does a felony charge stay on record in kansas?
There is no set length of time but you MUST have successfully completed the full term of your sentence before you can petition the court for expungement.

I believe Velocity is determined by speed and time.
