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).

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). To make these inventions be more significant, 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 capability 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 20th Century
By the time the 20th century arrived, vacuum 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’s (750).

In this essay, the author

  • Explains that electrical engineers research, develop, design, and test electronic components and products for commercial, industrial, medical, military and scientific applications.
  • Explains that the history of engineering goes back to the 19th century when alexander volta (1745-1827) made a remarkable discovery regarding the nature of electricity.
  • Explains that vacuum tubes were invented in the 20th century that could transmit weak electrical signals, which led to the invention of the radio broadcast system. these transistors were made from tiny bits of silicon to make microchips.
  • Explains the benefits that one receives from this job are common from one employer to another, but the exact benefits received are different from company to company.
  • Explains that electronic engineers need the most advanced and up-to-date equipment available to create enhanced electronics and improve on old products. they test products with high-tech equipment to make sure they are working in peak performance.
  • Explains the work ethics involved with electronic engineering, which is similar to most other jobs. engineers must make sure that their new products are not hazardous to people, and that there are no bugs or problems with the workings of the new product.
  • Opines that the key to advancement in the electronic engineering field is keeping up with technological advances.
  • Explains that the electrical engineering field is moving faster than average with the development of new technologies.
  • Explains that research, development and design, field service, sales and marketing are involved in the invention, design and operation of electrical and electronic systems and devices of all kinds.
  • Explains that most electrical engineers work in private industries such as television or telegraph companies. others are hired by the federal government for military, space programs or through engineering firms.
  • Explains that electronic engineers work on average 5 days a week, and 40 hours per week. however, there are exceptions that force engineers to work extra hours after work.
  • Explains that electronic engineers must have strong problem-solving abilities, mathematical and scientific capabilities, and a willingness to learn throughout their career.
