                                                       ELECTRONICS Definition of electronics:       electronics is a science which deals with the study of flow and control of electrons and the study of their behaviour and effects in vaccum,gases and semiconductors,and with devices using such electrons. A ctually everyone confuses between electronic and electrical.the basic difference between them is simple. electronics deals with the flow of charge through non metal conductors electrical deals with the flow of charge through metal conductors   here non metal conductors means semi conductors .we will see how semi conductors act like non metals below. metals can be classified as insulators ,semiconductors and conductors. INSULATORS: diamond SEMI CONDUCTORS: graphite, ger...
