A Diode Value is Connected to a Battery and a Load Resistance. the Filament is Heated, So that a Constant Current is Obtained in the Circuit. - Physics

Short Note

A diode value is connected to a battery and a load resistance. The filament is heated, so that a constant current is obtained in the circuit. As the cathode continuously emits electrons, does it become more and more positively charged?

Solution

No, the cathode does not become more and more positively charged. In the diode circuit,  the cathode of the diode valve is always connected to the negative terminal of the battery. So, the battery will supply the electrons to the cathode and the cathode will continuously emit electrons without becoming more and more positively charged.

Concept: Electron Emission
