What was Robert Millikan theory?
Work. During the 1890s the theory that electricity was conveyed by a miniscule unit, the electron, gained acceptance. In 1910 Robert Millikan succeeded in precisely determining the magnitude of the electron’s charge.

What did Millikan discover about the atom?
What was Robert Millikan’s discovery? Robert Millikan is most well known for discovering value of the elementary charge, which is the charge on a single electron. He measured the elementary charge using the famous oil drop experiment.
Why was Robert Millikan’s discovery important?
Robert Millikan’s accomplishments were the design and fine-tuning of experiments which unambiguously confirmed the most important scientific theories of his time, providing the implications for atomic theory. His oil drop experiment confirmed the existence of the electron and accurately determined its charge.
What conclusion did Millikan make?
Millikan, carrying out a long and tedious task that involved a set of collateral experiments, repeated the experiment numerous times, eventually concluding that the results obtained could be explained if there was a single, elementary charge (the value of which he determined) and the charges identified were integer …
How did Robert Millikan discover the charge of an electron?
Robert Millikan’s oil-drop experiment. 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. He found that all of the drops had charges that were simple multiples of a single number, the fundamental charge of the electron.
How did Millikan prove Einstein’s theory?
Millikan took Einstein’s theorized equation relating to the kinetic energy of the emitted electrons, K = hf – P where K is the kinetic energy of the electron, h is Planck’s constant, f is the frequency of the light shown on the metal, and P is the amount of work (energy) required to extract an electron from the metal.
When was Millikan born?
March 22, 1868Robert Andrews Millikan / Date of birth
Robert Millikan, in full Robert Andrews Millikan, (born March 22, 1868, Morrison, Illinois, U.S.—died December 19, 1953, San Marino, California), American physicist honoured with the Nobel Prize for Physics in 1923 for his study of the elementary electronic charge and the photoelectric effect.
How did Millikan prove his theory?
What is Millikan known for?
Robert Millikan was a physicist who discovered the elementary charge of an electron using the oil-drop experiment.
What is the conclusion of Millikan oil drop experiment?
Milliken’s Oil Drop Experiment Conclusion The charge over any oil droplet is always an integral value of e (1.6 x 10-19). Hence, the conclusion of Millikens Oil Drop Experiment is that the charge is said to be quantized, i.e. the charge on any particle will always be an integral multiple of e.

What did the oil drop experiment prove?
Millikan’s oil drop experiment proved that electric charge is quantized. At the time, there was still great debate whether electric charge was continuous or not. Millikan believed that there was a smallest unit of charge, and he set out to prove it. This was the big result of the oil drop experiment.
Why did Robert Millikan get a Nobel Prize?
The Nobel Prize in Physics 1923 was awarded to Robert Andrews Millikan “for his work on the elementary charge of electricity and on the photoelectric effect.”
