It provided a foundation for the entire field of atomic physics, validating the quantum theory at a time when many physicists remained skeptical. He repeated this process for numerous droplets, each time isolating a different particle.
Millikan Oil Drop Apparatus Design Explained: How the Iconic Experiment Measured the Electron's Charge
Here, "q" represents the charge on the droplet. Modern versions of the experiment, using advanced techniques and vacuum systems, continue to refine the value of the elementary charge, confirming Millikan’s original insight with extraordinary precision.
By precisely adjusting the voltage across the plates, Millikan could manipulate the electric field to perfectly balance the gravitational force on a single droplet, causing it to hover motionless. Using the known mass of the droplet, calculated from its terminal velocity as it fell through the air, and the known strength of the electric field, Millikan could apply the equation qE = mg.
Millikan Oil Drop Apparatus Design Explained: How It Quantized Electric Charge
The prevailing theories suggested that charge might be a continuous phenomenon, much like the flow of water. For centuries, electricity was a mysterious, invisible force, but this painstaking work quantified its smallest possible unit, forever changing the landscape of physics.
