1 янв 1909 г. - Millikan Performs Oil Drop Experiment

Описание:

Millikan performed the oil drop experiment in 1909. He devised a straightforward method of measuring the minute electric charge that is present on many of the droplets in an oil mist. The force on any electric charge in an electric field is equal to the product of the charge and the electric field. 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.
