Electrical Engineering
 
Work Performed
Electrical Engineers research, develop, design, and test 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 make 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, telephones, radios, and stereo systems (EGOE, 121).   Electrical engineers touch everyone lives through the things they have designed or created.   Electrical engineers have invented the lights in your house, the television, the stereo, the telephone, computers, and even your doctor’s blood pressure gauge (Stine 300).

History
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749).   He discovered that electrical current could be controlled and could flow from one point to another.   By the time 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 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 Telephone Company was established.   In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749).   Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749).
