Procedure and Measurement Technique Millikan's procedure involved spraying a fine mist of oil into a chamber situated between the charged plates, allowing droplets to fall through a small hole. After recording this terminal velocity, an electric field was activated to halt the droplet's descent, and the necessary voltage to achieve this suspension was precisely measured.
Statistical Analysis of the Elementary Charge in Millikan's Oil Drop Experiment
It stands as a testament to human ingenuity in isolating a fundamental constant and confirming the discrete structure of matter through meticulous observation. Initially, the droplet would accelerate due to gravity, but it quickly reached a terminal velocity as air resistance balanced the force.
The downward pull of gravity, determined by the droplet's mass, is counteracted by an upward electric force when a voltage is applied across two horizontal metal plates. The viscosity of the air and the droplet's fall speed were used to determine its mass via Stokes' law.
Statistical Analysis of the Elementary Charge in Millikan's Oil Drop Experiment
The Principle Behind the Experiment The core of the experiment relies on balancing two fundamental forces acting on a microscopic oil droplet. By observing the motion of tiny oil droplets suspended in an electric field, Millikan demonstrated that electric charge is quantized, existing only in discrete multiples of a basic unit.
