Electronics Information
Consumer electronics are electronic devices intended for everyday use by people. Consumer electronics usually find applications in entertainment, communications and office productivity. Consumer electronics are manufactured throughout the world, although there is a particularly high concentration of manufacturing activity in the Far East. One overriding characteristic of all consumer electronic products is the trend of ever-falling prices. This is driven by gains in manufacturing efficiency and automation, coupled with improvements in semiconductor design.
Selected biography
Georg Simon Ohm, (March 16, 1789 - July 6, 1854) a German physicist, was born in Erlangen and educated at the university there. His most important finding was Ohm's Law, which he first published in his pamphlet Die galvanische Kette mathematisch bearbeitet, in 1827. This work, the germ of which had appeared during the two preceding years in the journals of Schweigger and Poggendorff, has exerted an important influence on the development of the theory and applications of electric current. Ohm's name was adopted as the SI unit of resistance, the ohm (symbol Ω).

A bipolar junction transistor (BJT) is a type of transistor. It is a three-terminal device constructed of doped semiconductor material and may be used in amplifying or switching applications. Bipolar transistors are so named because their operation involves both electrons and holes. Although a small part of the base–emitter current is carried by the majority carriers, the main current is carried by minority carriers in the base, and so BJTs are classified as 'minority-carrier' devices.
The bipolar (point-contact) transistor was invented in December 1947 at the Bell Telephone Laboratories by John Bardeen and Walter Brattain under the direction of William Shockley. The junction version was invented by Shockley in 1951.
