ELECTRICITY I. DISCOVER OF ELECTRICITY About 600 B.C.‚ Thales‚ a Greek philosopher and scientist‚ observed that a piece of amber attracted small bits of “paper” or very thin wood shavings after it was rubbed with wool. He had discovered‚ in effect‚ static electricity. William Gilbert‚ an English scientist in the sixteenth century‚ found that many other different materials could be made to act like amber. Whenever these objects were rubbed against each other‚ they were able to attract each other

Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms‚ and an atom has a center‚ called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton‚ and the number of electrons in an atom is usually equal to the number of protons

Electricity has had a huge impact on our lives since the day it was discovered. It has changed the way we do everything. Electricity is used today with everything‚ just think about how many things you use everyday that need electricity.

Every single day we use electricity to make the things around us work. From the tape player to the electric pumps that send hot water to each of our homes everyday. Without electricity the lights go off‚ water is not heated‚ the television goes off‚ and outside the traffic lights do not work and as a result the city is immediately congested with traffic jams and choke ups in the street. Without that electricity we have everyday the basic things we use do not function. The book I chose to summarize

today ’s culture‚ electricity is a vital part of functioning as a society. Simple tasks‚ such as waking up at a designated time or enjoying a piece of music‚ are accomplished currently via electronic means. One only needs to consider the consequences of a relatively short power outage factories close down‚ phones and computers go dead‚ traffic slows to a crawl‚ food spoils in refrigerators to accurately observe how power-dependent our society has become. However‚ electricity is a constantly developing

effect was named after the scientist Luigi Galvani‚ who investigated the effect of electricity on dissected animals in the 1780s and 1790s. While experimenting in his lab‚ his scalpel touched the body of a frog‚ and he saw the muscles in the frog’s leg twitch. At that time he thought that he had discovered a new way of forming electricity. The term is also used to describe the bringing to life of organisms using electricity‚ as popularly associated with the 1831 revised edition of‚ Mary Shelley’s work

Filipino Scientists Contribution in the field of electricity Gregorio Zara Holder of doctorate in physics. Among Filipino Scientists‚ he is perhaps the most notable in the field of electricity. Zara formulated the Law of electrical resistance or what is known as the Zara Effect. This law states that all moving contacts between conductors produce a resistance to the passage electrical current which may be kinetic or permanent electrical resistance.
