ELECTRIC DISCHARGE MACHINING INTRODUCTION * Sometimes it is referred to as spark machining‚ * Its a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). * Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes‚ separated by a dielectric liquid and subject to an electric voltage. * One of the electrodes – ‘tool-electrode’ or ‘tool’ or ‘electrode’. * Other electrode - workpiece-electrode

Red’s electric powwow a musical group started by Ian Campeau and Bear Witness to give a voice to indigenous people. According to Damaris Colhoun In the starting stage of Electric powwow Campeau and witness faced public critics on the bases of their culture‚ color and creed. Starting with a small party for local indigenous students Campeau and Witness introduced mashed up of their own electronic music and powwow.” Pow Wows are the Native American people’s way of meeting together‚ to join in dancing

Globalization at General Electric Why do you think GE has invested so aggressively in foreign expansion? What opportunities is it trying to exploit? General Electric is one the largest industrial conglomerates in America. It has invested so aggressively in foreign expansion is due to the fact that they want to achieve their main goal which was to be number one or two globally in every business in which it participate. They took opportunities to exploit countries which having economic downturn

particularly eco-conscious‚ but they have now made their way into the mainstream. Most major motoring brands offer Hybrids with models like the Toyota Prius‚ the Honda CR-Z and the Lexus CT proving popular. They work by combining a fuel engine with electric batteries‚ which reclaims energy when the car brakes or converts energy from the petrol in the fuel engine. However‚ more manufacturers are developing ’plug in’ Hybrids‚ which offer the option to recharge more powerful batteries through a common

Electric Charge Lab John Doe Physics 1130 Oct 26th‚ 2010 Objective In this lab we will investigate some properties of electric charge‚ conductors‚ and insulators using everyday objects. Theory A charged object is any object that has an excess of negative or positive charge. Most objects are neutrally charged and we don’t normally experience their charge properties. Rubbing objects together and transferring some charge from one to the other is one way to create charged objects. Like charges

| Resistance and Electric Circuits | Lab 5 | | | The goal of the “Resistance and Electric Circuit” Lab was to determine the resistivity of a conducting wire given two known resistors. The main property of resistivity is that it represents how easily electrons can flow through a material. A Galvanometer is used to measure the current of the circuit and the Wheatstone Bridge is used to measure the resistances and determine the unknown resistance. This experiment also relates Ohm’s Law
