Basic Electronics

Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electronsin vacuum and matter. The identification of the electron in 1897, along with the invention of the vacuum tube, which could amplifyand rectify small electrical signals, inaugurated the field of electronics and the electron age.[2]Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, optoelectronics, and sensors, 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.
