Science Study Notes An electrically uncharged object is neutral. Conduction is not a method of charging an object. If electric charged stay in one spot‚ they are said to be static. In charging by induction‚ when a negatively charged rod is brought near a metal leaf electroscope the electrons in the electroscope move away from the rod. A statement that is not part of the Law of Electric Charges is that neutral objects are attracted to uncharged objects. The purpose of a GFCI is to protect people from

students of electricity begin their study with what is known as direct current (DC)‚ which is electricity flowing in a constant direction‚ and/or possessing a voltage with constant polarity. DC is the kind of electricity made by a battery (with definite positive and negative terminals)‚ or the kind of charge generated by rubbing certain types of materials against each other. As useful and as easy to understand as DC is‚ it is not the only “kind” of electricity in use. Certain sources of electricity (most

Line & Beyond The materials‚ which allow electric current to pass through them‚ are good conductors of electricity. On the other hand‚ materials‚ which do not allow electric current to pass through them easily‚ are poor conductors of electricity. You know that metals such as copper and aluminum conduct electricity whereas materials such as rubber‚ plastic and wood do not conduct electricity. Conductivity of Liquid To test whether a liquid allows electric current to pass through it or not‚ we

Thomas Edison’s contributions to society through the science of electricity are undeniable and extremely significant. However‚ in the competition between his promoted DC electricity and George Westinghouse’s AC electricity‚ Edison employed some seemingly questionable motives in an attempt to succeed in the three-fold motive; enhance his reputation as a leading scientist‚ reap the profits that would come‚ and protect his established reputation which would be ‘dented’ by losing. Edison’s reputation

Who Discovered Electricity ? From the writings of Thales of Miletus it appears that Westerners knew as long ago as 600 B.C. that amber becomes charged by rubbing. But other than that‚ there was little real progress until the English scientist William Gilbert in 1600 described the electrification of many substances and coined the term "electricity" from the Greek word for amber. As a result‚ Gilbert is called the father of modern electric power. In 1660‚ Otto von Guericke invented a crude machine
