IV Characteristics of a Diode

This is a teacher or student controlled, realistic 3d simulation of a virtual experiment that allows you to plot the IV characteristics of a diode.  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).   Diodes have the property that they essentially only let current flow in one direction.   

The user can move the control the power supply, alter the connection of the LED, and the change the variable resistor.  The user is free to move anywhere within the laboratory in order to interact with the apparatus.
