Taking Forward and Reverse Readings
For forward bias the p side (anode) is made positive. Raise the voltage in small steps and note both meters each time: the current stays very small until the barrier potential of the junction is overcome, then rises steeply for a small further increase in voltage. For reverse bias the diode is connected the other way round. The current is now only a tiny leakage current, far below the forward values, and it changes little as the reverse voltage grows.
Working Out Resistance from the Graph
Plot current against voltage, with the reverse readings in the third quadrant. The ratio V/I at any point gives the static (DC) resistance, while the ratio ΔV/ΔI taken along the forward curve gives the dynamic resistance, which falls as the current rises. The point where the forward curve turns sharply upward is the knee (cut-in) voltage. Keep the forward current well inside the diode’s rating while readings are taken.
