NT1310 Unit 9 Assignment 1 A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962‚ early LEDs emitted low-intensity red light‚ but modern versions are available across the visible‚ ultraviolet‚ and infrared wavelengths‚ with very high brightness.When a light-emitting diode is switched on‚ electrons are able to recombine with holes

INVISIBLE BROKEN WIRE DETECTOR 1 1. INTRODUCTION In our day to day life we are dealing with electricity as well as so many electrical equipments. In this electrical equipment the household appliances play a major role. So the fault occurring with them is also a major problem. Generally the fault seen is the breaking of wire inside the two layer or three layer cables or the short circuit between them. Portable loads such as video cameras‚ halogen flood lights‚ electrical irons‚ hand drill

INTRODUCTION The electronics distribution industry is inherently a volatile one because it is based on technologies that are constantly evolving and improving as time passes. The industry has already survived three major technological revolutions and can probably be expecting another one in its long-term future. These "revolutions" usually concern the refinement or replacement of a component that is fundamental to all electronic circuitry. While demand for related component parts remains relatively
