In this simulator you can explore the behavior of the Electrophorus. You can attach both a flag (thin conducting strip) and a pendulum as indicators of the surface charge state of the Electrophorus. An option to color charged surfaces red and blue provides a model view of the process. Below, the electrophorus is brought closer to a blue charged insulator. The changing thickness of the red and blue coloring on the lower and upper surface of the Electrophorus suggest the polarization that is occurring.
Below, the Electrophorus is touched to the charged insulator, and is then removed. The Electrophorus now has a net blue charge. The last picture shows a grounding hand discharging the Electrophorus.
A Graphics palette includes tools that enables you to annotate and draw on the simulator, and to take snapshots.
