Item Picture
written by Michael Davidson
This item is an interactive Java tutorial that simulates the movement of free electrons when voltage is applied across a conductor.  As the user adjusts the current flow, the resulting changes are represented on both a macro and nanoscale.   The design of the simulation helps the beginner understand how electron collision causes resistance within a system.  This applet is part of a larger collection sponsored by Florida State University.

Please note that this resource requires Java Applet Plug-in.

Topic: Electricity and Electrical Energy
Unit Title: Resistance and Ohm's Law

As students adjust current flow in this Java simulation, the resulting changes are represented on both a macro and nanoscale.   This activity helps the beginner understand how electron collision causes resistance.  Try teaming this simulation with the one above on Ohm's Law.
