Electrostatic Field • An electrostatic field is a phenomenon that is very similar to a magnetic field. When an object is electrically charged‚ it creates an electrostatic field. If an object has an excess of electrons‚ then it’s considered to have a negative charge. If an object has fewer electrons than its surrounding environment‚ though‚ it’s considered to be positively charged. Just like with magnetic fields‚ two objects that are oppositely charged will attract each other. This scientific

Windmill Electricity | | Mankind been harnessing the wind’s energy for many years. From Holland to traditional farms around the world‚ windmills were used in the past for pumping water through primative irrigation systems or used to grind grain. Then‚ the wind turned large "sails" which were connected by a long vertical shaft that was attached to a grindnig machine or to a wheel that turned and drew water from a well. Today’s turbines - can utilize the energy of the wind to turn large metal

PaedDr. Dagmar Rusková‚ PhD. Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian American inventor‚ electrical engineer‚ mechanical engineer‚ and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system Tesla gained experience in telephony and electrical engineering before immigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers‚ setting up laboratories

Cook Misty Stroud‚ PhD CHM 151; CRN 25017 1 March 2013 Tesla vs. Edison Everyone knows who Thomas Edison is‚ and many attribute the “invention of electricity” to Edison‚ but this is simply not accurate. The truth is‚ while Thomas Edison did patent and market DC‚ or direct current‚ electricity‚ he did not “invent” electricity‚ and as a matter of fact‚ much of his work was actually basically stolen from other scientists‚ among them‚ one brilliant scientist‚ Nikola Tesla. We are all taught

Who had the greatest impact on our technology? It was none other than Nikola Tesla. Tesla invented alternating current‚ wireless telegraphy‚ the radio etc. Many of which Tesla invented at the 1893 Chicago World`s Fair. Before Tesla began inventing his parents believed he would do something great. Born July 10‚ 1856 in Smiljan‚ Croatia‚ Tesla was said to be “a child of the light.” Early in his life he was exposed to inventing. In school he always had perfect grades and an overachiever.
