Electrical EngineeringWork PerformedElectrical Engineers research, develop, design, and test electronic components, products, and remainss for commercial, industrial, medical, military, and scientific applications (Cosgrove 749). They are concerned with devices that use small amounts of electricity that assume up electronic components such as integrated circuits and microprocessors. By applying principles and techniques of electronic design they design, develop, and manufacture products such as computers, telephones, radios, and stereo systems (EGOE, 121). Electrical engineers touch everyone lives by the things they have designed or created. Electrical engineers have invented the lights in your house, the television, the stereo, the telephone, computers, and however your doctor&8217s blood pressure gauge (Stine 300). HistoryThe narrative of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electrici ty (Cosgrove 749). He discovered that galvanic current could be control lead and could flow from one point to another. By the duration the mid-19th century came about the rules for electricity were being established. During this time electromagnetic inductor was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell think Company was established. In 1878, the light bulb was finally invented by doubting Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday&8217s electric motor from 1821, Nicholas Tesla invented a more than in force(p) and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended t o make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities by means of the use of electricity, and it also led to the creation of the telephone communication system (750).Into The 20th CenturyBy the time the 20th century arrived, clean tubes were invented that could transmit weak electrical signals which led to the formation of electromagnetic waves that led to the invention of the radio broadcast system (750). These vacuum tubes were discovered to be able to transmit currents through solid material, which led to the creation of transistors in the 1960&8217s (750).
