About this Simulation

This interactive simulation models how free electrons move through metallic conductors to create electric current. Learners can visualize the positions and movements of positive ions and negative electrons arranged in a lattice structure, exploring how charge carriers drift through the conductor when electrical potential is applied.

Learning objectives: Understand the microscopic mechanism of electric current in metals | Visualize the role of free electrons and fixed positive ions in electrical conductivity | Explore how electron density and arrangement affect current flow
