V - Voltage between the two plates at the edges of the container
n - Number of ionized gas molecules
N - Number of neutral gas molecules
Things to Notice
Drift Speed
Restart the simulation! Try viewing the whole container as one, and notice that the ionized molecules move to the right more or less with the drift speed. Try adjusting the sliders; notice that increasing the voltage increases the drift speed, but increasing the number of molecules decreases it.
