This is a virtual experiment allows the user to plot the current and voltage relationship for a diode.  The voltage is set on the power supply and voltage across the LED can be changed by rotating the variable resistor knob.  There are two multimeters that allow readings to be taken for the voltage across the diode and current flowing through it.  The LED can be seen to glow as the voltage is increased.
