Aplicações da física na eletrônica: relé fotoelétrico

Abstract

The electronics are in all elds of human activity and changed forever the way we live, work and communicate with others. The electronics provide entertainment, convenience and information in general makes it easy and productive daily life. All this technological evolution provided by the electronics was only possible thanks to the e orts of various physical scientists engineers and inventors who are dedicated to discovering and creating mathematical and physical concepts that led to the creation of various electrical and electronic devices that have contributed to the scienti c and technological growth of society. Among the many advances can highlight the creation of the incandescent lamp, the creation and manipulation of electromagnetic waves, which later evolved with the creation of radio and television. In this work, a re ection on the applications of physics in electronics, as well as the explanation of the operation of some electronic components used in large scale in various devices. Finally built a photoelectric relay in order to approach and understand the basic physical concepts involved in electronic devices.
