WebTo calculate the bulk resistance of a diode, the following formula is used: RB= ∆VF/∆IF. where VF is the forward voltage dropped across the silicon diode and IF is the forward current flowing through the diode. Note: For silicon diodes, the barrier voltage for current flow to occur is above the point of 0.7V. WebThe relationship between the current flowing through the diode and the voltage due to the applied voltage in forward bias and reverse bias is shown by a graph. Thus showing the voltage and diode current through the graph is called VI characteristics of the diode. If = forward bias current. Vf = forward bias voltage. VR= reverse bias voltage.
