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.
