NOTE: This paper explains the theory and uses of the electric generator‚ and explains the differences between AC and DC generators. It also includes a glossary and a bibliography. --------------------------------------------------- ELECTRIC GENERATORS In its most basic definition‚ an electric generator is a machine that produces electricity. Generators produce almost all of the electricity used by people. They supply the electric power that runs machines in factories‚ provide lighting‚ and operate

is to use the electric motor instead of gasoline one. An electric car is a car that powered by an electric motor rather than a regular gasoline engine. There are several major differences between gasoline and electric cars. First of all‚ “the electric motor will replace the gasoline engine” (“How Electric”‚ 2004). Secondly‚ “the electric motor is powered by a controller” (“How Electric”‚ 2004). Thirdly‚ “the controller gets power from the rechargeable batteries” (“How Electric”‚ 2004). In

The Universal Museum – a valid model for the 21st century? Introduction In October 2002‚ the International Group of Organisers of Largescale Exhibitions‚ also known as the Bizot Group — a forum comprising directors of 40 of the world’s major museums and galleries — gathered in Munich for their annual informal discussion.1 The meeting was convened specifically to address the problem of how to confront the growing number of requests for repatriation of objects from ‘universal’ museums and in particular

Universal Health Care Many would argue that here in the United States‚ we have the best healthcare in the world. People from all over the world come to the U.S to use the most up to date medical resources. Is the reputation that the U.S holds warranted‚ and if so‚ what is the cost? The average annual cost per U.S resident is $7‚681.These costs rank us among the highest of industrialized nations (Lundy 2010). According to the National Scorecard on U.S Health System Performance (2008)‚ the U.S compared

Lincoln Proposed Resolution: 1.1 International Expansion Team • The root of Lincoln Electric’s troubles began with the quick expansionist mindset of George Willis. The main trouble was the speed of the expansion. Lincoln Electric should have formed international expansion team focusing on the key areas that initiates a market analysis to spearhead strategic directions of developing good governance framework and promoting inclusive growth. They are also responsible to evaluate alternative mode

help the environment and also save lots of money. Electric cars are something everyone should invest in because it saves a lot of money. Many people probably think that it will cost a lot of money because of the installation but in the long run you would actually save more than gasoline does. People can also make it convenient to have a charger installed in their homes so that they don’t have to pay or travel far just to recharge. Using electric cars will keep our environment from being polluted

11 important Problems of Universalization of Education and their Remedies SWASTIK Universalization of Elementary Education is Constitutional directive. Education is every body’s birth-right and it is binding on any government to provide facilities for education for children who are born and reach the school-going age. It was stipulated to achieve Universalization within 10 years from the introduction of Constitution and that is by 1960. But it is now more than three decades after the scheduled time

point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12‚x‚ the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2‚ Q1=-3.5μC‚ Q2=5.1 μC‚ and r=9.3 cm we get F=-18.57 N. It’s important to realize that getting a negative force value means the charges attract. The direction of that attraction is determined

Chapter 1 The History of Electric Transformer INTRODUCTION: Transformer is a device that transfers electric energy from one circuit to another‚ usually with a change in voltage. Transformers work only with a varying electric current‚ such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the high levels needed to transmit the electricity efficiently. Other transformers

A cultural universal (as discussed by George Murdock‚ Claude Lévi-Strauss‚ Donald Brown and others) is an element‚ pattern‚ trait‚ or institution that is common to all human cultures worldwide. Evolutionary psychologists hold that behaviors or traits that occur universally in all cultures are good candidates for evolutionary adaptations.[1] Some anthropological sociological theorists that take a cultural relativist perspective may deny the existence of cultural universals: the extent to which these
