The term space charge is applied to the cloud of electrons that is formed in the interelectrode space between cathode and plate. Since it is made up of electrons, this cloud constitutes a negative charge in the interelectrode space that has a repelling effect on the electrons being emitted from the cathode. The effect of this negative space charge alone, therefore, is to force a considerable portion of the emitted electrons back into the cathode and prevent others from reaching the plate.

The cloud of electrons formed in the space between cathode and the plate is called space charge. The space charge is negative and hence has a repelling effect on electrons emitted from the cathode. The amount of the plate current depends on the space charge and the relative strength of the electric field set up by the positive plate voltage.

The Plate Current
The Plate Voltage

Plate current is the flow of electrons from cathode to the plate and their return to the cathode through the external circuit. Plate current flows in a diode when the plate is made positive with respect to the cathode. No current flows when the plate is negative with respect to the cathode. This is called unidirectional conduction.
