101seminartopics.com INTRODUCTION We are now living in a world driven by various electronic equipments. Semiconductors form the fundamental building blocks of the modern electronic world providing the brains and the memory of products all around us from washing machines to super computers. Semi conductors consist of array of transistors with each transistor being a simple switch between electrical 0 and 1. Now often bundled together in there 10’s of millions they form highly complex‚ intelligent

(kay rap)DEFINITION OF TERMS AC (alternating current) - In electricity‚ alternating current (AC) occurs when charge carriers in a conductor or semiconductor periodically reverse their direction of movement. Household utility current in most countries is AC with a frequency of 60 hertz (60 complete cycles per second)‚ although in some countries it is 50 Hz. The radio-frequency (RF) current in antennas and transmission lines is another example of AC. The usual waveform of an AC power circuit is a sine

In electronics‚ an integrated circuit (also known as IC‚ microcircuit‚ microchip‚ silicon chip‚ or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices‚ as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material. Integrated circuits are used in almost all electronic equipment in use today and have revolutionized the world of electronics. A hybrid integrated circuit is a miniaturized electronic circuit constructed

Hazards of Electronic waste Electronic waste‚ e-waste‚ e-scrap‚ or Waste Electrical and Electronic Equipment (WEEE) describes loosely discarded‚ surplus‚ obsolete‚ or broken electrical or electronic devices. Informal processing of electronic waste in developing countries causes serious health and pollution problems. Some electronic scrap components‚ such as CRTs‚ contain contaminants such as lead‚ cadmium‚ beryllium‚ mercury‚ and brominated flame retardants. Even in developed countries recycling
