Question

Ratio of forward bias to reverse bias resistance in a given diode using i gaph

Answer 1

The opposition offered by a diode to the changing current flow I forward bias condition is known as its AC Forward Resistance. It is measured by a ratio of change in voltage across the diode to the resulting change in current through it. From the figure A above it is clear that for an operating point P the AC forward resistance is determined by varying the forward voltage (CE) on both the sides of the operating point equally and measuring the corresponding forward current (DF).
