Hello friends,
electronics is the branch of physics and engineering specialization, which studies and employs systems whose operation is based on the conduction and control of the flow of electrons or other electrically charged particles.
Edison was the first to observe the thermionic emission in 1883, by placing a sheet inside a light bulb to avoid blackening produced by the carbon filament in the glass ampoule.
When the metallic sheet was positively polarized with respect to the filament, a small current was produced between the filament and the sheet.
For many, electronics are very complicated with all electronic circuits and schematics, but we must say that for many people it is a spectacular world, mainly to students who identify with the subject.
