- Nicola Tesla
The Answer:
And, the answer for the the question is :
Explanation:
Robert Milikan conceived of the oil drop experiment in 1909, and it was successful in demonstrating both the existence of electrons and the fact that they have a defined electric charge. He worked with cloud chambers or containers of water vapor, in which water droplets would form around charged atoms before falling due to the force of gravity. By manipulating the intensity of the electric field within the chamber, he was able to slow the descent of a single droplet, effectively using electricity to fight gravity. Millikan’s tests, which were designed to estimate the charge that is carried by a single electron, were conducted with oil.
The determination of the value of a single electron’s charge was a major breakthrough in the field of physics, and it has had a profound impact on our understanding of the behavior of subatomic particles. The value of the electron’s charge was first determined by American physicist Robert Millikan in a series of experiments known as the oil drop experiment.
Millikan’s experiments involved suspending tiny oil droplets in a chamber and subjecting them to an electric field. By carefully measuring the motion of the droplets and the strength of the electric field, Millikan was able to determine the charge of a single electron with remarkable accuracy.
Through his experiments, Millikan established that the charge of a single electron was approximately 1.6 x 10^-19 coulombs, a value that has since been confirmed through a wide range of experiments and observations.
The discovery of the value of the electron’s charge was a major milestone in the development of modern physics, and it paved the way for further research into the behavior of subatomic particles and the fundamental nature of matter.
the principles and theories developed through Millikan’s work continue to inform and shape our understanding of the natural world, from the study of particle physics to the development of new technologies and materials.
Whether you’re a student of physics or simply interested in the remarkable achievements of one of history’s greatest scientists, the story of Robert Millikan and his groundbreaking work on the value of the electron’s charge is a fascinating and inspiring one that is well worth exploring.
