5924 times 10 to the power of negative 19 coulombs. Second, an adjustable electric field created by the voltage across the plates exerts an upward electrical force on the charged droplet.
Measuring Electron Charge with the Millikan Oil Drop Experiment
Procedure and Ingenious Setup Millikan designed a chamber where droplets of oil were sprayed into the space between two horizontal metal plates. Legacy and Impact on Modern Physics The importance of the Millikan oil drop experiment extends far beyond a single measurement.
The Millikan oil drop experiment was not just a clever demonstration of electric forces; it was a meticulous operation that finally allowed scientists to isolate the fundamental charge of the electron. Millikan correctly interpreted this as the fundamental unit of electric charge, the charge carried by a single electron.
Measuring Electron Charge with the Millikan Oil Drop Experiment
A microscope allowed the team to peer into this chamber and observe the droplets clearly. By repeating this process for numerous droplets, Millikan noticed a distinct pattern: the charges were always integer multiples of a single, smallest value.
