ELECTRONIC CIRCUIT ANALYSIS

INRODUCTION OF THE ELECTRONIC CIRCUIT ANALYSIS :

In science, we study about the laws of nature and verification and in technology, we study the applications of these laws to human needs.
Electronics is the science and technology of the passage of charged particles, in a gas vacuum or semiconductor.SOLIDWORKS

Before electronic engineering came into existence, electrical engineering flourished. Electrical engineering mainly deals with motion of electrons in metals only, where as Electronic engineering deals with motion of charged particles (electrons and holes) in metals, semiconductors and also in vacuum.

Another difference is, in dectrical engineering, the voltages and currents are very high KV, and Amperes, where as in electronic engineering one deals with few volts and mAo Yet another difference is, in elect{ical engineering; the frequencies of operation are 50 Hzs/60Hzs.

In electronics it is KHzs, MHz, GHzs, (high frequency). The beginning for Electronics was made in 1895 when H.A. Lorentz postulated the existence of discrete charges called electrons. Two years later, JJ Thomson proved the same experimentally in 1897. In the same year that is in 1897, Braun built the first tube based on the motion of electrons, the Cathode ray tube (CRT).

In 1904 Fleming invented the Vacuum diode called ‘valve’. In 1906 a semiconductor diode was fabricated but they could not succeed, in making it work. So semiconductor technology met with premature death and vacuum tubes flourished.ELECTRONIC CIRCUIT ANALYSIS
