People don’t know electricity can kill them, so many people die from electricity. Anyone can take simple safety precautions when being around and working with electricity. That can reduce the risks of injury or death from electricity and electrical equipment, there are a lot of ways to protect workers and, the general public. Some injuries […]

Transistor A transistor is a semiconductor device used to amplify and switch electronic signals. It is made of a solid piece of semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of […]

ROBOT DESIGN Section 1 – Requirements 1.1 Introduction Robot is a kind of automatic machine, which has particularly a series of similar competences as human-being, such as sensing capability, planning capability, moving capability and so on. The word ‘Robot’ was referred by Czech writer Karel Čapek in his play R.U.R (Rossum’s Universal Robots), which was […]

Abstract: This is the globe of VLSI . Presently all most all the folks are utilizing know-how in numerous types like mobiles, i-pods, i-telephones etc. , Each and every a single enjoys technological innovation but only a number of know about VLSI structure in entire world style and design and its doing work. Coming to […]

INTRODUCTION 1.0 INTRODUCTION Private branch exchange system (PBXs) operates as a connection within private organizations usually a business. Because they incorporate telephones, the general term “extension” is used to refer to any end point on the branch. The PBX handles calls between these extensions. The primary advantage of PBXs was cost savings on internal phone […]

Power factor: The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load to the apparent power, and is a dimensionless number between 0 and 1 (frequently expressed as a percentage, e. g. 0. 5 pf = 50% pf). Real power is the capacity […]

CHAPTER 1 INTRODUCTION 1.1 Project Overview A factor of main economic importance and safety in electrical utilities and industrial customers of electricity is dependent on the operation of the power transformer. In the current economic situation, most of the supply utilities and industries tighten their control on production spending of capital and make savings in […]

Introduction Alight-emitting diode(LED) is asemiconductorlight source. LEDs are used as indicator lamps in many devices and are increasingly used for otherlighting. Introduced as a practical electronic component in 1962,early LEDs emitted low-intensity red light, but modern versions are available across thevisible,ultravioletandinfraredwavelengths, with very high brightness. When a light-emittingdiodeis forwardbiased(switched on),electronsare able torecombinewithelectron holeswithin the device, […]

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 […]
