Electronics is a branch of physics and technology concerned with the behavior and movement of electrons in semiconductors. Electronics is an important area relating to engineering study. The concept of electronics is used for electronic components integrated circuits and electrical systems. The common electronic components include capacitors, resistors, diodes, transistors and these components are found to be passive or active in nature. Thus, Circuits and components can be divided into two categories and they are analog and digital. Electricity in modern day plays an important role in every individual's life. The electronics revolution is rapidly changing our world whether we are at home, at school, at office or work or out for a shopping we mostly surrounded by electronic machines and equipments.
