Uses of the thermionic diode tube

Fitted to the diode base, the valve is used for experiments on thermionic emission, in which the heated cathode emits electrons that reach the anode only when the anode is positive.

  • Plotting the anode current against anode voltage characteristic of a vacuum diode
  • Showing that a diode valve conducts in one direction only
  • Studying the effect of filament heating on emission current
  • Replacing a failed valve in an existing diode apparatus
