The organization chosen for the analysis Ceylon Electricity Board (referred to as CEB hereafter)‚ which is the Sri Lankan government organization for generation‚ transmission and distribution of electricity for local industrial and domestic consumption. Following a general introduction to the services by the organization and the structure of it and market competencies‚ the economies

producing A.C. and D.C electricity. There are two type of electric current it is known as direct current (DC). The other one is known as alternating current (AC). However‚ an electric current can be produce by moving a magnet inside a coil‚ wire‚ so the size of this induces current and it is able to increase by moving the magnet faster. This is using a stronger magnet‚ so increasing the number of the turns‚ coils. It may be able to increase its area but the dynamo is a type of electricity generator.

HISTORY OF ELECTRICITY IN KERALA – Dr D Shina S N COLLEGE‚ Kollam‚ Kerala‚ India email - achushina@gmail.com ORIGIN AND GROWTH OF ELECTRICITY The history of electricity can be traced back to the eighteenth century. The first instance of sensing the phenomenon of electricity was the accidental observation of what was later found out to be neon glow by Framas Bauksbw in 1709 at the Royal Society in London. Luigi Galvani observed moving of the legs of a dead frog when touched with a metal scalpel

Unit 3 The Characteristics of Electricity ( pg 296 ) Day 1 Electrostatics - study of static electricity Neutral objects - materials that do not carry a charge Conductors allow charges (electrons) to flow through them easily. E.g. metal Therefore no matter how hard that you rub a metal tap no static charge will build up because the electrons that you are giving the tap just keep on moving up the tap and down the water line until they reach a ground. Insulators do not allow charges

The inept governments of PML-N and PPP‚ that still consider themselves vital to democratic dialogue within the provinces‚ failed to create dialogue within provinces‚ on the most important

How has electricity changed the world we live in since 2000? What is an invisible thing that is everywhere and is always there for our comfort? Electricity. It’s almost wherever you look. It usually can’t be seen and has been helping us since the 1840s. Starting with the invention of telegraph by Samuel Morse at around 1840‚ electricity started making our lives better and changing our lives dramatically. Going from telegraph‚ to telephone‚ to radio and to television. But how has this invisible

Topology With Reduced DC-Link Voltage Rating for Load Compensation With Nonstiff Source Srinivas Bhaskar Karanki‚ Nagesh Geddada‚ Student Member‚ IEEE‚ Mahesh K. Mishra‚ Senior Member‚ IEEE‚ and B. Kalyan Kumar‚ Member‚ IEEE Abstract—The distribution static compensator (DSTATCOM) is used for load compensation in power distribution network. In this paper‚ a new topology for DSTATCOM applications with nonstiff source is proposed. The proposed topology enables DSTATCOM to have a reduced dc-link voltage

Static Electricity Physics Lab #1 June 24‚ 2011 Purpose The purpose of this experiment is to explain the different aspects of static electricity‚ including effects of electrical charges on small-uncharged objects‚ electrical attraction and repulsion‚ creation of electrical charge‚ practical uses of electrical charges‚ and measurement of electrical force between electrical charges. Findings Electric current is the flow of electric charge. Some materials become electrically charged when rubbed

My research is to determine if electricity moves better through thick wires or through thin wires. For this experiment I used two size D batteries‚ two flashlight bulbs‚ one 6.5 inch thin steel wool piece‚ one 6.5 inch thick steel wool piece‚ two 2 inch pieces of straw‚ and some electrical tape. Steel wool is a material made from thin fibers of steel made into a pad. (http://www.wisegeek.com/l-what-is-steel-wool.htm) There are many uses for steel wool. It can be used for sanding furniture‚ removing

Difference between Static and Dynamic RAM The journey of dynamic and static RAM was initiated in 1960s which was readily developed in 1970s. In recent days‚ the technology is much more user friendly. RAM is classified into two types: Dynamic RAM and Static RAM. Static RAM uses a form of flip-flop to circulate data. It uses almost six transistors for its functioning. On the other hand‚ Dynamic RAM (DRAM) is typically charged on the capacitor in it. Static RAM holds the data in the
