From the following ads place the requested information:In what year was electronics created?The operation of the following device is based on the Edison effect. Edison was the first to observe the thermionic emission in 1883 by placing a sheet inside a light bulb to prevent the blackening of the carbon filament in the glass ampoule. When the metal sheet was positively polarized with respect to the filament, a small stream occurred between the filament and the sheet. This happened because the electrons of the atoms of the filament, when receiving a great amount of energy in the form of heat, escaped the attraction of the nucleus (thermoionic emission) and, crossing the empty space inside the bulb, were attracted by the Positive polarity of the blade.
