Millikan, working at the University of Chicago, accepted this challenge, aiming to transform a theoretical concept into a measurable constant through ingenuity and patience. 602 x 10 -19 coulombs, emerged as the fundamental unit of electric charge.
Measuring Fall and Rise Velocities in the Millikan Oil Experiment
Critical components included: A precision atomizer to create oil droplets of varying sizes. Microscope for visual tracking of individual droplet motion.
Stopwatch for timing fall and rise velocities. Apparatus and Experimental Setup Millikan's apparatus consisted of a horizontal metal chamber with two parallel plates acting as capacitor plates.

Furthermore, the experiment's methodology influenced generations of physicists, demonstrating the power of isolating single particles to probe fundamental constants. This value was essential for calculating Avogadro's number, linking the microscopic world of atoms to the macroscopic scale chemists used daily.
