their 80’s. What many people didn’t know is that they were rivals. Edison had a rival in the race to develop electricity. His name was George Westinghouse‚ and he was very interested in alternating current. Edison bought Tesla’s ideas‚ and developed an AC system that lit up the 1893 Chicago World’s Fair. Three years later an AC system began turning the energy of Niagara Falls into electricity. Before that Edison relied only on direct current which only went up to one mile while alternating current

when I completed my science fair project I have always worked on electrical currents‚ the flow of current from its positive charge to its negative charge. What helped me understand this concept was when we had the electricity unit my freshman year. I combined my knowledge of electricity with magnetism that same year in my science fair project: I created an electromagnet. The strength of the electromagnet depended on the amount of volts used. This project gave me the chance to go where as one of the

institution‚ as I believe that a Masters degree will help me to realize my ultimate goal‚ which is to develop myself as a well educated electrical engineer and promote my existing career in related industries. As a high school student we had an electricity lesson in which we had to make a simple motor using wooden board‚ nails and coated wire and battery. After assembling the materials when I connected the system to the 3 volt battery‚ the rotor‚ made by winded nail‚ started rotating suddenly .it

and escape routes should be established. Regarding electrical safety‚ it is advisable that all electric devices are treated with respect. To this end‚ wiring installation should be checked by approved contractors to ensure that overall system of electricity supply functions properly. To avoid electrical hazards‚ appliances with damaged or worn flexes should not be used; at that wire flexes cannot be used in conjunction. Portable mains-operated appliances should be kept out of the bathroom. Electric

Unlike other power plants that rely on coal or other ¬¬¬fossil fuels to create electricity for homes and businesses‚ geothermal power plants use superheated fluids from the earth’s geothermal energy to generate electricity. When magma heats up the water from underground‚ it creates superheated fluids. When these super-heated fluids reach the surface they will be turned into steam. This steam will then power a turbine‚ which will in turn power a conductor. The conductor will then produce electrical

of powder coating begins in the late 1940s and early 1950s‚ where organic polymers were being spray coated in a powder form on metallic bases. Later‚ in 1960 the electrostatic powder coating system was created. This method uses the properties of electricity to apply a high-solids coating to any conductive material. The painting equipment is charged with one electrical polarity‚ while the metal objects to be painted are charged with the reverse polarity. When the coating is sprayed it is attracted to

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

Nikola Tesla was a famous inventor‚ electrical and mechanical engineer. George Westinghouse was a famous entrepreneur and engineer who invented the railway air brake and was a pioneer of the electrical industry They were trying to decide which electricity system‚ either direct current (DC) or alternating current (AC)–would become normal. During the War of the Currents‚ Edison was trying to promote the direct-current system (DC)‚ where electrical current would flow progressively in one direction.
