Electronics This article is about the technical field of electronics. For personal/home-use electronic devices, see consumer electronics . For the scientific magazine, see Electronics (magazine) . Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes , transistors , diodes , integrated circuits , associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit . The science of electronics is also considered to be a branch of physics and electrical engineering . [1...
