About this Simulation

This simulation models the classic Millikan oil drop experiment, allowing learners to observe how charged oil droplets behave under competing gravitational and electric forces. Students can adjust field strength, droplet size, and other variables to measure the charge of individual droplets and discover the quantised nature of electric charge.

Learning objectives: Understand how electric fields affect charged particles | Determine the elementary charge through experimental manipulation | Explore the relationship between force balance and particle charge quantisation
