IV Characteristics of a Lightbulb

This is a teacher or student controlled, realistic 3d simulation of an experiment that allows you to plot the IV characteristics of a lightbulb.  That is, you can plot how the current changes when you change the voltage (The ‘I’ is for current, and the V is for voltage).   This depends on the resistance of the bulb which changes depending on the voltage.  Effectively the bulb gets hotter and hotter as the voltage increases until it is eventually white hot.  As the temperature of the metal filament gets hotter its resistance changes. 

The user can control the power supply and the variable resistor.  The user is free to move anywhere within the laboratory in order to interact with the apparatus.
