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). 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). These transistors were made from tiny bits of silicon which could be produced to make microchips. From transistors, microprocessors could be made which led to the technological era that we are in today, where everything from microwaves and digital watches to computers are run by these mini-processors (750).

Nature Of Work

Research, development and design, field service, sales and marketing are involved in the invention, design, construction, and operation of electrical and electronic systems and devices of all kinds (Cosgrove 698). Electronics engineers work with how computers and electrical systems are wired, how appliances work, and how electrical circuits are used in an endless number of applications (Cosgrove 698).

Researchers are involved with issues relating to future applications (Kunz 12). They are interested in testing and examining basic problems involved in their studies (12). From these they will then apply principles and techniques of Electrical Engineering to come up with possible solutions to the problem.

Development/Design Engineers are placed with the task of creating, designing, and constructing new products by use of electrical and electronic systems and devices of all kinds (Cosgrove 698). They then test the new product in real world scenarios for safety, efficiency, and compatibility.

Production engineers are the organizers. They set up a manufacturing plan for the product their company will be making (Kunz 12).

Field Service engineers work between the manufacturer and the consumer by installing the product for consumers and by helping them with any technical support they may need (Kunz 12).

The specialties that one can commit to in engineering can vary significantly. For example, they can include acoustics, signal processing, lasers, robotics, electromagnetic compatibility, geosciences & remote sensing, or even vehicular technology (Stine 300).

Work Environment

Most electrical engineers work in private industries such as television or telegraph companies (BLS 5). Others are hired by the federal government for military, space programs or through engineering firms (BLS 5). Others work on a contract basis where they are self-employed, and work independently as contractors or consultants (BLS 5).

Electronic engineers work mainly in a comfortable indoor environment usually in their offices and at their desks (Kunz 14). Engineers who are involved in research and design also work in specially developed laboratories where they can conduct experiments and test their products. These laboratories have a lot of high tech equipment that allow engin
