Electricity is one of the most important energies in people’s daily life. Without electricity‚ life will be tough and boring. We could only use candles for illumination and firewood for cooking. There would be not PCs‚ no TVs‚ and even no radios. Electricity brings us a great life and it is an affordable energy. The local electricity price in Fairbanks is about 16 cent per Kilowatt-hour. However‚ the waste of electricity is a serious problem in Wickersham hall. When you walking outside the Wickersham

conductor of electricity. If the electrons in an atom can’t be moved from their orbits at all‚ the material is an insulator. If at least some of the electrons can be moved‚ the material is a resistor. Two of the best-known conductors of electricity are silver and copper. The atomic structures of the silver and copper atom are compared in Figure 6. Note that both atoms have only one electron in the outermost orbit. This makes silver and copper excellent conductors of electricity. Silver is

History of Electricity Our knowledge of electricity has started from very humble beginnings when you look at where we are today. Electricity has been around for as long as humans have. When lightning strikes ancient people may not have understood what it was or why it happened‚ but they at the very least witnessed it happen. Nature acted as a sort of catalyst to spark the curiosity of early people. It was only until sometime between 624 BC and 546 BC where an understanding of electricity began to

Windmill Electricity | | Mankind been harnessing the wind’s energy for many years. From Holland to traditional farms around the world‚ windmills were used in the past for pumping water through primative irrigation systems or used to grind grain. Then‚ the wind turned large "sails" which were connected by a long vertical shaft that was attached to a grindnig machine or to a wheel that turned and drew water from a well. Today’s turbines - can utilize the energy of the wind to turn large metal

Wonders of Electricity Electricity is the greatest gift of science to mankind. We have reached a point of our civilization when electricity is used for all purposes. Without it‚ our existence will be impossible. Electricity is a source of energy. It is produced by a battery or a coil of wires or by dynamo machine. It is produced in thermal station and also in hydro-project. There are various wonders of electricity. The most important of all is electric fan and electric light. These two things

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

Electricity was first researched by Thales of Miletos around 600BC. He conducted a few experiments on static electricity in which he believed that friction made amber become magnetized. Other than the fact that people knew that eels produced electric shocks‚ electricity was little more than an intellectual curiosity for over 2000 years. Until 1600 when someone from England discovered the lodestone effect when amber with static would attract small objects towards it. In the 18th century‚ Benjamin
