Electronics is the discipline dealing with the development and application

of devices and systems involving the flow of electrons in a vacuum, in gaseous

media, and in semiconductors. 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.

 Electronic component

An electronic component is any physical entity in an electronic system used to affect the electrons or their associated fields in a manner consistent with the intended
function of
the electronic system. Components are generally intended to be connected together,
usually by being soldered to a printed circuit board (PCB), to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator).
Components may be packaged singly, or in more complex groups as integrated circuits. Some common electronic components are capacitors, inductors, resistors, diodes, transistors, etc. Components are often categorized as active e.g. transistors and thyristors or passive e.g. resistors, diodes, inductors and capacitors.

History of electronic components

Vacuum tubes (Thermionic valves) were among the earliest electronic components.[5] They were almost solely responsible for the electronics revolution of the first half of the

twentieth century. They took electronics from parlor tricks and gave us radio, television, phonographs, radar, long-distance telephony and much more.

They played a leading role in the field of microwave and high power transmission as well as television receivers until the middle of the 1980s.Since that time, solid-state devices have

all but completely taken over. Vacuum tubes are still used in some specialist applications such as high power RF amplifiers, cathode ray tubes, specialist audio equipment, guitar amplifiers and some microwave devices.

Television Electronics


Television (TV) is a telecommunication medium used for transmitting moving images in monochrome (black and white), or in colour, and in two or three dimensions and sound.

The term can refer to a television set, a television program (“TV show”), or the medium of television transmission. Television is a mass medium for advertising, entertainment and news. Make money on Electronics Engineer click here
