WebThe classical example of thermionic emission is the emission of electrons from a hot metal cathode into a vacuum (archaically known as the Edison effect) used in vacuum tubes. However, the term "thermionic emission" is now used to refer to any thermally excited charge emission process, even when the charge is emitted from one solid-state region ... WebMay 14, 2013 · Edison Holding an Edison Effect Tube (West Orange) The science books today call it “thermionic emission” [the conversion of heat directly to electricity], but its original name was the Edison effect. It began with the emission of electrons from a hot light bulb filament, soon to become the very basics of vacuum tubes, which led to practical ...

WebUsing the Edison Effect to control electricity, Edison opened his first experimental power station in the early 1880s. Though later perfected using the alternating current (AC) system, the electronics age commenced with Edison's power system. Over the course of the twentieth century, appliances and household devices were either redesigned or ... WebThe Edison effect happens when electrons would flow from a heated element to a cooler metal plate, in a vacuum. Now the Edison effect has an interesting feature. The electrons can flow only one way. Only from the hot element to the cool plate, never the opposite way. A good comparison would be water flowing through a check valve.
