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

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

What is Electricity? Electricity is one of the most powerful forces in our lives. As a matter of fact‚ it can even kill you. The most vital part of electricity is called electric energy. This is what we commonly think of when we hear the word electricity. “Electricity” reminds us of anything that we plug into an electrical outlet in order to make it work‚ such as lights‚ refrigerators‚ video games‚ microwaves‚ and computers. Scientists discovered ways to produce electric energy in large amounts

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

Early History of Electric Power Date Event Pictures 1800-1819 Early electric experiments were performed with DC. In 1800‚ Alessandro Volta published a description of a silver/zinc battery‚ acknowledging that he did not know how it worked. In 1807‚ Humphry Davy constructed a practical battery (the picture will be immediately familiar to anyone who works with UPS systems)‚ and demonstrated both incandescent and arc light. • Volta’s famous bi-metalic frog twitch (I did this one myself as a boy..

Moral Issues of Abortion Crystal Lamb Soc. 120 Tracy Green October 22‚ 2010 Moral Issues 1 Abortion is a volatile subject and one that most people feel passionate about. There are several ethical components of the abortion debate that help form ones opinion on whether or not abortion is moral. In this piece I’d like to focus on the rights of everyone involved in the decision to either terminate a pregnancy or carry to term (2006). Much emphasis is placed on a woman’s right to choose’‚ yet

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 Project Electricity is a form of energy involving the flow of electrons. Now-a-days electricity has become quite-common in the world. Everybody sees the wonderful work of electricity. The lights on the streets are lit by the electric current. Electric fans work in the court‚ high court and office-rooms. Trains and trams are run by the electric power. They even made cars that run off electricity. So‚ electricity is no longer a strange thing. Electricity is a basic
