Sentence examples for electron tube from inspiring English sources
noun
Any of several devices consisting of a sealed chamber, either evacuated or filled with gas at low pressure, in which an electric current flows between electrodes.
Scientists later determined that this effect was explained by the thermionic emission of electrons from the hot to the cold electrode, and it became the basis of the electron tube and laid the foundation for the electronics industry.
This phenomenon was first called "Hammer's phantom shadow," but when Edison patented the bulb in 1883 it became known as the "Edison effect". Scientists later determined that this effect was explained by the thermionic emission of electrons from the hot to the cold electrode, and it became the basis of the electron tube and laid the foundation for the electronics industry.
