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

Electricity is important to life. A vast number of machines which are invented nowadays cannot be operated without it. As a matter of fact‚ electricity is used mostly in four main areas: industry‚ public health‚ media and transportation. First of all‚ electricity plays an integral part in industry. Thanks to the invention of electricity‚ a lot of equipment has been invented including computers‚ subways‚ bulbs‚etc .... .Electricity is the crucial factor in operating most devices. As a matter of

HISTORY OF ELECTRICITY Depite what you have learned‚ Benjamin Franklin did not "invent" electricity. In fact‚ electricity did not begin when Benjamin Franklin at when he flew his kite during a thunderstorm or when light bulbs were installed in houses all around the world. The truth is that electricity has always been around because it naturally exists in the world. Lightning‚ for instance‚ is simply a flow of electrons between the ground and the clouds. When you touch something and get a shock

In summer seasons electric fans‚ air conditioning plants are used to provide us with cool atmosphere. In winter‚ heating plants are used to keep the room warm. Electric bells‚ press and stove are things of every-day use. People keep refrigerators in their homes to keep their food in a fresh condition. Indeed electricity serves as a faithful domestic servant in daily

Lecture Notes: Basic Electricity Fall 2011 This course module introduces the basic physical models by which we explain the flow of electricity. The Bohr model of an atom – a nucleus surrounded by shells of electrons traveling in discrete orbits – is presented. Electrical current is described as a flow of electrons. Ohm’s law – the relationship between voltage‚ current and electrical resistance – is introduced. Learning Objectives Understanding the basic principles of electricity is a foundational

Jennifer Nelson Unit 3 Assignment 1 Date due: July 12 Date submitted: July 12 Define Key Terms Electrical circuit: A complete loop of material that conducts electricity. Frequency: When describing energy that acts like waves‚ the number of times that the entire waveform repeats per second. Amplitude: When describing energy that acts like waves‚ when graphing the waveform centered on the X axis‚ and graphing some kind of power (for example‚ voltage) on the Y axis‚ the amplitude is the maximum

Abstract Nikola Tesla was the most underappreciated scientist of all time. In spite of his lack of funding‚ trust‚ and support; Tesla was one of the most successful inventors that the world has ever seen. From AC generators to wireless transmission of electricity to invisible death rays; Tesla envisioned countless world changing inventions. With proper funding and support‚ we can only speculate how many more theories he would have successfully tested. The Amazing Nikola Tesla Technology

contributions in the fields of electromagnetism and wireless radio communications. He made the tesla coil which is an electrical resonant transformer circuit designed by Tesla in 1891. It is used to produce high-voltage‚ low-current‚ high frequency alternating-current electricity. Tesla arrived in the United States in 1884. At the age of 28‚ and by 1887 had filed for a series of patents that described everything necessary to generate electricity using alternating current‚(AC) He created the A/C electric

Not much over a hundred years ago‚ electricity‚ except in the form of lightning‚ was an unknown force. Its discovery was due to Michael Faraday‚ the great English scientist. On one occasion‚ about 1830‚ he was showing one of his early experiments to a distinguished company at the Royal Institution in London. He showed that when a magnet was brought suddenly near a coil of wire‚ a slight current of electricity was produced in the wire. Afterwards a lady said to him‚ "But‚ Professor Faraday‚ even if
