Source sentences:
text: A stream of electrons emitted by the cathode in electrical discharge tubes.
text: In a tube, the anode is a charged positive plate that collects the electrons emitted by the cathode through electric attraction.
text: When held negative with respect to the cathode, the control grid creates an electric field which repels electrons emitted by the cathode, thus reducing or even stopping the current between cathode and anode.
text: Similarly, in a phototube, electrons emitted by the cathode are collected by the anode and again, electrons are moving away from the interface in the anode.
