electrical EngineeringWork PerformedElectrical Engineers research, develop, design, and taste electronic components, products, and systems for commercial, industrial, medical, military, and scientific applications (Cosgrove 749). They are concerned with devices that use small amounts of electricity that obligate up electronic components such as integrated circuits and microprocessors. By applying principles and techniques of electronic engineering they design, develop, and manufacture products such as computers, addresss, radios, and stereo systems (EGOE, 121). Electrical engineers touch everyone lives through the things they come designed or created. Electrical engineers have invented the lights in your house, the television, the stereo, the call, computers, and even your doctor&8217s blood pressure gauge (Stine 300). HistoryThe history of engineering goes back into the 19th century when black lovage Volta (1745-1827) made a remarkable discover regarding the nature of elec tricity (Cosgrove 749). He discovered that electrical current could be controllight-emitting diode and could flow from one distributor point to another. By the clock the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the electrify 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 winner of the telephone, Bell Telephone Company was established. In 1878, the light bulb was eventually invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday&8217s electric motor from 1821, Nicholas Tesla invented a more efficient and precedentful electric motor in 1888 (749). To make these inventions be more significa nt, effort was expended to 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 competency of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).Into The twentieth CenturyBy the time the 20th century arrived, make clean tubes were invented that could transmit weak electrical signals which led to the system 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).
