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

In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electrons in the windings to flow through the external electrical circuit. It is somewhat analogous to a water pump‚ which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling through a turbine or waterwheel‚ an internal combustion engine‚ a wind turbine‚ a hand crank

first applications of electricity was the first incandescent light bulb in around 1870. The electric overhaul of society obviously brought many fresh new dangers with it‚ but it eliminated some of the old ones‚ like the naked flames of gas lighting that was commonly used in homes and factories then. The Joule heating effect that can be found in light bulbs is also present in electric heating. Electric heating has been thought of as wasteful in the past because in order to create that heat energy

The Electric Car has a history but is there a future in the UK or will there be a better option? The invention of the first Electric Car was in 1830 but was not perfected until the creation of rechargeable batteries in 1859. By 1912 50 companies were producing 34‚000 electric cars. Once the development of the electric starting motor occurred and the price of fuel was cheap then the electric cars industry vanished. The oil crisis in the 1970’s caused some re-emergence of electric cars but the

Lincoln Electric 1. Problem The problem foe Lincoln Electric is that they are having less than expected revenues from their overseas venture. Their management system worked so well in their original facility in Ohio. They had such high confidence in the way they made their products there that they thought that if they do what they did in another country‚ they will reap the same benefits. When they applied the same management principles in other countries‚ they had net losses that are so high

I. Physical Features Electric eels are not really eels‚ they are actually ostariophysians‚ but have a strong physical resemblance to true eels. . An electric eel is mostly tail. The internal organs are compressed into the anterior (front) 1/5th of the body‚ and the rest of the fish consists of the long‚ electricity-producing tail. The tail contains the electric organs: Sachs’ organ‚ Hunter’s organ‚ and main organ. Extending down the entire tail region is an elongated anal fin. There are no dorsal

pushed away‚ or repelled‚ each other. The evidence showed that electric force made matter either attract or repel other matter. Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge – positive and negative charge. The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel

Refusing Bailout Money When the economy took a down turn many companies started having cash flow problems. Several automakers like General Motors and Chrystal‚ took bailout money in 2008 from the United States government in order to keep their company from financial ruin. These companies took 24.9 billion dollars in bailout money. Ford was the only American automaker that did not take

The two most important issues that Lincoln Electric is faced with are as follows. First‚ the inability to meet customer demand because of the shortages in supply creates opportunities for competing firms to enter the industry. What resources and capabilities does Lincoln Electric have that can mitigate this threat of entry. Second‚ the emphasis put on the monetary incentive plan leaves the company vulnerable in economic hardships. How can Lincoln Electric continue to encourage competition and quality

1 ELECTRIC MOTORS I. Introduction Electric motors are considered to be important mechanical devices. They usually convert the electrical energy coming from the mechanical device into its kinetic energy to make it work (Petingco and Resurreccion‚ 2011). In this exercise‚ the students were tasked to use an example of an electric motor‚ identify its parts‚ and make it work. All electrical motors are equipped with stator and rotor. Stator is known as the stationary part of an electric motor
