Thomson had already discovered the electron, a subatomic particle carrying a negative charge. The equation governing this suspension combined Stoke's law for drag, gravitational force, and the electrical force (qE), where 'q' represented the charge on the droplet.
Exploring Charge Quantization with the Millikan Oil Drop Experiment
The Genesis of a Revolutionary Experiment By 1909, J. 602 × 10⁻¹⁹ coulombs.
591 × 10⁻¹⁹ coulombs, which was within 1% of the currently accepted value of 1. Today, the experiment remains a cornerstone of physics education, offering a tangible demonstration of quantum principles.
Millikan Oil Drop Experiment Charge Quantization
This level of precision was unprecedented for its time and demonstrated the power of careful experimental design. This 'elementary charge' became a cornerstone of modern physics, solidifying the idea that electricity is not a smooth continuum but a product of discrete particles.
