Observing the Quantum Nature of Charge While the ability to hold a droplet stationary was a significant achievement, the true genius of the experiment emerged from the repeated trials conducted on numerous droplets. The core procedure involved carefully balancing the downward pull of gravity with the upward push of the electric field, causing a specific droplet to hover motionless.
Evidence for Multiple Charges in the Oil Drop Experiment
The scientific community needed a method to isolate and measure a single charge, a task that required exceptional control over microscopic particles. By measuring the terminal velocity of a droplet during its free fall, they could calculate its mass and, consequently, the gravitational force acting upon it.
The Genesis of a Revolutionary Experiment Before Millikan's meticulous investigations, the existence of discrete electric charges remained a compelling hypothesis rather than an established fact. This conceptual leap provided the framework for translating the abstract nature of electricity into a quantifiable value.
Evidence of Multiple Charges in the Oil Drop Experiment
By applying a voltage across the plates, Millikan could create an electric field that could be adjusted to exert an upward force on the negatively charged droplets. Millikan, working at the University of Chicago, devised an apparatus that would allow him to suspend tiny droplets of oil in an electric field, effectively creating a measurable balance between gravitational force and electromagnetic force.
