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

Solid state physics II Testing a Peltier Element Abstract The purpose of the experiment was to investigate the cooling properties of a Peltier element and specifically the relation between the electric current through the element and the temperature in a refrigerator cooled by the element. The “refrigerator” consisted of a cavity in a block of polystyrene foam with the Peltier element covering the opening of the cavity. A fan on top

prodding‚ and deeper review‚ Edison realized how getting involved with this issue would help his personal business cause. Thomas Edison ’s light business was quickly losing ground to rival George Westinghouse. He knew he was widely respected as an electrical engineer and claimed not to change his stance on executions‚ but acknowledged the necessity and offered a humane alternative with electricity. More specifically and strategically‚ he offered up George Westinghouse ’s alternating current dynamos

should be a part of every cable installation kit. Continuity Testers: This is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the tester. The tester consists of an indicator in series with a source of electrical power - normally a battery‚ terminating in two test leads. If a complete circuit is established

Solar Absorbers and the Future of Electricity Solar Absorbers and the Future of Electricity By James Folta Electricity is what we use to power things at home or at school. You can probably look around right now and see an electrical outlet or two. Everything that we plug into one of these outlets uses electricity. But where does this electricity come from? Right now we have a few ways to make electricity. Some are better than others. There are some scientists who are trying to find
