Assertion: diode's voltage | /r/HasProperty | applied to the plate
Facets:
Source sentences:
text: If a negative voltage is applied to the plate, electrons cannot escape from the cathode, and no plate current flows.
text: When a positive voltage is applied to the anode (or plate), electrons emitted from the heated cathode flow to the plate and return to the cathode through an external power supply.
text: If an alternating voltage is applied to the plate, current flows only during the time when the plate is positive.
