In an experiment, the saturation in the plate current in a diode is observed at 240 V. But a student still wants to increase the plate current. It can be done if the : (a) filament current is increased (b) filament current is decreased (c) plate voltage is decreased (d) plate voltage is increaed further |

To increase the plate current further the filament current should be increaed, so that more electrons are produced.</span></span></p> | |
