In 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

Born on November 8‚ 1923 in Jefferson City‚ Missouri‚ Jack Kilby was a determined intellectual. After receiving a B.S. degree in Electrical Engineering from the University of Illinois‚ Mr. Kilby decided to get his M.S. in the same field from the University of Wisconsin. He then began his career in Milwaukee in 1947‚ working in the Centralab Division of Globe Union Inc. "developing

CHOKE COIL IN TUBE LIGHTS… We saw in the last section that gases don’t conduct electricity in the same way as solids. One major difference between solids and gases is their electrical resistance (the opposition to flowing electricity). In a solid metal conductor such as a wire‚ resistance is a constant at any given temperature‚ controlled by the size of the conductor and the nature of the material. In a gas discharge‚ such as a fluorescent lamp‚ current causes resistance to decrease. This is

century alternator made inBudapest‚ Hungary‚ in the power generating hall of a hydroelectric station In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit. The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling through a turbine or waterwheel‚ aninternal combustion engine‚ a wind turbine‚ a hand crank

Theme : Electrical Sector and Chemical Engineer a) “The Chemical Engineer – His Role in Electrical Manufacturing” by N.R. Maleady The article is about the role of chemical engineer in manufacturing transformers in the electrical manufacturing sector. The important components of the transformer are copper wire‚ cellulosic insulation‚ insulating varnish and dielectric liquid. Wire enamel or resin is the insulting structure for copper wire. The resin can either applied as a solution or in solventless
