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 `70 V`?

Text Solution

Verified by Experts

For plate current 20 mA, we find the
voltage 50 V or 60 V.
Hence it acts as the saturation current.
Therefore, for the same temperature, the
plate current is 20 mA for all other values
of voltage.
Hence the required answer is 20 mA.
