Robert Millikan Net Worth 2024, Age, Height, Bio, Birthday, Wiki!

Who is Robert Millikan and what did he discover?

Robert Millikan was a physicist who discovered the elementary charge of an electron using the oil-drop experiment.

What was Robert Millikan's theory?

Robert Millikan Atomic Theory Millikan’s work demonstrated that electrons did have a discrete, quantifiable charge. Thomson had also already calculated the charge-to-mass ratio of an electron, so once Millikan was able to measure the elementary charge, the mass of an electron could also be calculated.

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.

How did Robert Millikan determine the charge of an electron?

Millikan was able to measure both the amount of electric force and magnitude of electric field on the tiny charge of an isolated oil droplet and from the data determine the magnitude of the charge itself.

Who discovered the electron?

J.J. Thomson decided to find out for sure. Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric and magnetic fields.
