As per the diagram:
v-I characteristics of SCR is a graph of anode current I A on y-axis & anode to cathode Voltage plotted on x-axis v-I characteristics can be split into two parts namely Forward Characteristics & Reverse Characteristics.
Now why does the Vak suddenly drops to Vh during conduction... This is unlike a diode where the voltage remains constant even after avalanche breakdown...
Please can anyone explain this isusue to me!
