Thermionic Current (Noun)
Meaning
An electric current produced between two electrodes as a result of electrons emitted by thermionic emission.
Classification
Nouns denoting natural phenomena.
Examples
- The thermionic current between the cathode and anode was measured using a sensitive ammeter.
- Thermionic current is a critical component in the operation of vacuum tubes used in early electronic devices.
- The heat generated by the filament was sufficient to produce a significant thermionic current between the electrodes.
- Researchers studying thermionic emission were interested in understanding the factors that affected the magnitude of the thermionic current.
- The space charge effect was found to be an important factor limiting the thermionic current in high-voltage applications.
