In an experiment, the saturation in the plate current in a diode is observed at

240V

. But a student still wants to increase the plate current. It can be done, if

View answer and explanation

Correct option: D

The filament current is increased

The correct answer is D (The filament current is increased) because increasing the filament current increases the temperature, leading to more electron emission and thus a higher plate current even after saturation.
