Objective:

Measure Each Diode and resistors.
Graph resistor curves.
Isolate section of the curve to prove that the 5 or 6 curvesare identical with 5 or 6 values.

VI Graphs:

Silicon Diode

Clear Diode

Green Diode

Red Diode

LED's:

Yellow LED

Red LED

Clear LED

Green LED

The Two Resistors

Diode

Zener Diode

Conclusion:

Essentially The graphs are identical. As shown above.
