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

The overuse of electricity affects the ecosystem in several ways. The overuse of electricity can lead to an increased carbon footprint‚ increased climate change‚ reduction in supply‚ and high energy costs. The abiotic factors that contribute are electricity‚ smoke‚ temperature‚ climate‚ and mining. The biotic factor that affects it is people. Leaving your laptop plugged in all the time will use up 300 kilowatts an hour each year. A natural consequence of overusing energy is increased costs for you

CONCEPT OF WIRELESS ELECTRICITY (Wi-Tricity) Our forefathers marveled at the invention of glowing light bulbs by Thomas Edison in 1879. However‚ to us 21st centurions‚ the light bulb is nothing out of the ordinary. When computers‚ cell phones‚ laptops‚ iPods‚ etc. were invented our antennas tweaked. Now this is what you call invention! However‚ as time’s progressing we are getting used to these devices. In fact‚ charging all these appliances has become so very cumbersome. Each appliance has its

Electricity and magnetism run nearly everything we plug in or turn on. Although it’s something we take for granted‚ it has taken hundreds of years of experimentation and research to reach the point where we flick a switch and the lights go on. Ancient Greeks knew rubbing amber generated static electricity‚ but they didn’t know why. The Greek word for amber is elektron. People knew about electricity for a long time. Ancient Greeks noticed that if they rubbed a piece of amber‚ feathers would

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
