"thermionic cathode"of or relating to or characteristic of thermions
Definition that contains thermionic
- diode a thermionic tube having two electrodes; used as a rectifier
- triode a thermionic vacuum tube having three electrodes; fluctuations of the charge on the grid control the flow from cathode to anode which makes amplification possible
- thoriate impregnate with thorium oxide to increase thermionic emission
- pentode a thermionic tube having five electrodes
- rectifying tube a thermionic tube having two electrodes; used as a rectifier
- tetrode a thermionic tube having four electrodes
- rectifying valve a thermionic tube having two electrodes; used as a rectifier
- thermionics the branch of electronics dealing with thermionic phenomena (especially thermionic vacuum tubes)
- thermionic current an electric current produced between two electrodes as a result of electrons emitted by thermionic emission
