The central motivation for Millikan's work was to determine this fundamental constant with unprecedented accuracy. The key was to balance the downward gravitational force with the upward electric force, allowing for the calculation of the charge on a single droplet.
Balancing Electric Field and Gravity to Isolate Electron Charge
Millikan and his graduate student Harvey Fletcher in the early 20th century, this inquiry provided the first direct measurement of the elementary electric charge, the fundamental unit carried by a single electron. Repeated measurements across numerous droplets to identify the common factor.
602 × 10⁻¹⁹ C. By applying a voltage across the plates, the droplets could be made to rise, fall, or remain stationary.
Balancing Electric Field and Gravity to Isolate Electron Charge
Using these kinematic measurements and adjusting for air viscosity effects described by Stokes' law, the team could isolate the charge *q* on a specific droplet. More profoundly, the results showed that every droplet's charge was an integer multiple of this smallest unit.
