electricity generation
Basically the thermionic rays are fast moving electrons. They originate in the region having an excess of electrons. So originate from the cathode.
Rechardsons equation
thermionic emission
Thermionic valve
thermionic emission occurs when the filaments are heated to a certain degree, causing the electrons to boil off and form a space charge or electron cloud.
Thermionic emission
What is mean by thermionic generation is that electricity is created as a hot electrode will emit electrons onto a cold electrode. Elements like cesium are often used to help bridge the gap and improve the output.
