electricity generation
A thermionic thermometer uses the thermionic emission of electrons from a heated filament to measure temperature. When the temperature increases, the emission of electrons also increases, allowing for a correlation between temperature and electron emission. These thermometers are used in high-temperature applications and can provide fast response times.
No, incandescent light bulbs do not emit electrons by thermionic emission. Instead, they produce light by heating a filament to such a high temperature that it emits visible light due to incandescence. Thermionic emission typically refers to the emission of electrons from a heated cathode in vacuum tubes or electron guns.
The process you are referring to is called thermionic emission. It occurs when electrons are emitted from a heated cathode due to their increased thermal energy, allowing them to overcome the surface barrier and escape into the surrounding environment.
A thermionic thermometer is a device that measures temperature by detecting the electrons emitted from a heated surface. It relies on the thermionic emission phenomenon, where electrons are released from a heated cathode and collected at an anode to generate a measurable signal related to the temperature of the cathode.
Thermionic emission occurs at the cathode in a cathode ray tube, which is a vacuum tube that generates electron beams. When the cathode is heated, electrons are emitted and accelerated towards the anode, leading to the generation of cathode rays within the tube.

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 of electrons is due to the heating of a metal, which causes electrons to gain enough thermal energy to overcome the work function of the metal and escape into free space. This process results in the emission of electrons from the metal surface.
