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‚ electricity

Definition Of Static Electricity Static electricity is the buildup of electrical charges on the surface of some object or material. Static electricity is usually created when materials are pulled apart or rubbed together‚ causing positive (+) charges to collect on one material and negative (−) charges on the other surface. Results from static electricity may be sparks‚ shocks or materials clinging together. Static electricity is the accumulation of electrical charges on the surface

Electricity’s impact on Society Electricity has had multiple impacts on society both positve and negative. Electricity has had an effect on everyone in the world‚ even though some people have no understanding or have no use for electricity. For example‚ there are tribes in the Amazon who have never seen a lightbulb who have never beared witness too the heracy of Big brother and yet they are still effected by electricity. The chainsaws which cut down their beloved forests are designed by a man called

Electrostatic Field • An electrostatic field is a phenomenon that is very similar to a magnetic field. When an object is electrically charged‚ it creates an electrostatic field. If an object has an excess of electrons‚ then it’s considered to have a negative charge. If an object has fewer electrons than its surrounding environment‚ though‚ it’s considered to be positively charged. Just like with magnetic fields‚ two objects that are oppositely charged will attract each other. This scientific

Electricity and Magnetism History Electromagnetism Originally electricity and magnetism were thought of as two separate forces. This view changed‚ however‚ with the publication of James Clerk Maxwell’s 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions‚ all of which have been clearly demonstrated by experiments: 1. Electric charges attract

Why Save Electricity? With the rising costs and shrinking economy more and more people are acting responsible and seacrhing for reasonable ways to save electricity. The other reason apart from these are that saving electricty will bring down your electicity bills‚ save you money and decrease pollution. Although many people have shifted to renewable sources such as solar power‚ there are other electricty saving tips too which will help you to conserve power. Electricity Saving At Home Replace

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
