Electric Cars An electric car is a vehicle which gets power from one electric motor or more‚ and an electric car use electrical energy to store batteries or another energy storage device. The developmental history of electric cars is very long‚ and the first automobile all over the world was an electric car. However‚ electric cars had two terrible disadvantages: the problem of energy technology and mileage limit around 20 century. The problems made electric cars disappeared from citizens eyes for

Electrical Machines I Prof. Krishna Vasudevan‚ Prof. G. Sridhara Rao‚ Prof. P. Sasidhara Rao 2 Basic Principles As mentioned earlier the transformer is a static device working on the principle of Faraday’s law of induction. Faraday’s law states that a voltage appears across the terminals of an electric coil when the flux linkages associated with the same changes. This emf is proportional to the rate of change of flux linkages. Putting mathematically‚ e= dψ dt (1) Where‚ e is the induced

that Nature is almost Physics (apart from the fact that the word Physics itself is derived from Greek "physis" meaning nature). Physics is all around us. We can find Physics as the backbone for any daily life example such as an electric light‚ electricity‚ the working of our vehicle‚ wristwatch‚ cell phone‚ CD player‚ radio‚ plasma TV set‚ computer‚ and - the list goes on Physics and its principles are integrated with almost everything you do. A few of the things physics controls are how: •

Project report submitted on: Transformers Class: 12 Submitted to: Mr. Jonny beaver‚ Physics teacher Submitted by: Mohammed Al Khabori 19 February 2011 Theoretical report Transformers I have generated series of questions‚ regarding the transformers‚ which are to be researched and answered. They are the following: * What is the history of transformers? * What is a transformer? * Which principle/laws does the transformer obey? * How can we construct a transformer?

electro-chemical devices. CONTRIBUTION to SOCIETY Alessandro Volta‚ Italian physicist‚ known for his pioneering work in electricity. Volta was born in Como and educated in the public schools there. By 1800 he had developed the so-called voltaic pile‚ a forerunner of the electric battery‚ which produced a steady stream of electricity. In honor of his work in the field of electricity‚ the electrical unit known as the volt was named in his honor. Marie Curie AUTOBIOGRAPHY Inventor: Marie Curie

To do and not to do with electricity Hey! Are you among those who enjoy doing their work on their own? If yes‚ then this one’s for you!! I understand how good it feels to have your work done on your own‚ save money and somehow‚ getting into the expert’s shoes. One thing most of these people forget is that it can just be lethal down the line doing things one doesn’t know about. Especially‚ when it comes to doing an electrician’s job! That’s when a professional electrician comes into the picture

Domestic Technology in the past There is information about the history of domestic technology and its effect on gender involvement in the home (ca 1850 - 1990). These are mainly changing standards‚ the nature of family life‚ and new roles for women in the home. Instead of removing housework‚ domestic technology accompanied to a re-definition of how this work must be organized and done. Housework in the 19th century The 19th century home The organization‚ physical effort

alternative source of energy is the fact wind speed must be at least greater than 10 miles per hour‚ and this is not a constant situation (Green living‚ 20130). However‚ when wind speed is greater than 12 miles per hour‚ can generate 70 % more electricity‚ and the best approach to ensure such scenario is building platforms for the fans at higher altitudes (Green living‚ 2013). In case wind increases too much‚ it can damage the wind turbines‚ therefore most of the wind turbines automatically shut

As a network administrator for a company‚ you want to configure an IP route between two routers. Of static and dynamic routing‚ which is more appropriate? Explain your answer in 200 to 300 words. I think that the best routing choice for this would be a static IP; this is because for a company you may want to have the ability to check the log for problems. Using a dynamic IP would mean that the people that logged on to their device would be almost invisible because they could
