The plate current in a diode is 20 mA when the plate voltage is 50 V or 60 V. What will be the current if the plate voltage is 70V?
Given the plate current is 20 mA for 50 V and 60 V, i.e. 20 mA is the saturation current.
∴, for a given temperature current remains same for all voltages. . i.e. for 70 V current is 20 mA.
