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).
Germinating tobacco seeds are a very delicate thing to do. Seeds are spread out on the surface of a seedbed to be nursed until they are strong enough to be out in a field. The “nursery” takes about 2 months of supervising the growth of the plant and to control diseases and pests (Akehurst, 1968). Before replanting in a field, producers have to assess a field site. There needs to be a reliable
...rming relationships with employees was made clear by being efficient and fair to preserve and inspire their workforce. These results can be further studied in a dissertation that is duplicated in a different culture to test the consistency of its findings. Using the information from these two studies, it is clear that transformational leaders behaviors have an impact on their follower’s perception (Bacha and Walker, 2012; Cho and Dansereau, 2010).
As the late 19th century progressed, technological ideas and inventions began to thrive. The notion that technology would impact life as we know it was an unbelievable idea to comprehend. People had no idea that something so simple such as the light bulb would become so vital to them and for century’s to come. Inventions such as, the typewriter, barbed wire, telephone, Kodak camera, and electric stove were created, however the major inventions created and use tremendously today are, Medicine, Electricity, and Transportation.
With the invention of the hydroelectric dam in the early 1920’s, many citizens can now afford electricity in their homes. Along with that came inventions such as the telephone, revolutionizing the way that we communicated. Before the telephone, communication could only happen through mail. Depending on the situation, that could take 6-7 days. Then came inventions like the electric refrigerator, stove, iron and radio.
Theory of transformational leadership is founded on the notion that conditions of injustice spark the need for social change (Bass, 1996). Transformational leadership is characterized by behaviors that are geared toward relational aspects of the organization (Goodnow & Wayman, 2009). Transformational leaders intrinsically motivate followers to function as a collective to achieve a common aim (Bass, 1996). This model of transformational leadership provides a set of leadership practices that are linked to the key elements of Burns’s theory and builds on the work of Bass and Avolio. In his work he elaborated the difference between the uses of transactional leadership compared to transformational leadership. Leadership styles can be used
Companies have to pay corporation taxes on their taxable profits. This is why the corporation taxes depend on how much profit a business makes.
Lifelong learning is developing a new skills or knowledge through lifelong, voluntary, and self-motivated pursuit of education for professional reasons or personal purpose. In other words, lifelong learning is the process of one educating oneself from early childhood to late senior years. A lifelong learning idea represents that, people learned by their selves, in groups, and from each other. Also, they learn by making real model solution to new products where we have to apply our skills and they take their skills that they learned and apply it to a real-life practice field. There are some factors that play an important role in lifelong learning through self-directed learning such as: creativity, self-concept as an effective learner, and openness to learning opportunities. Dave Truss, in a philosophy essay, states, “The goal of education is to enrich the lives of students
To be an effective leader, leaders need to have good followers and cannot exist without them (DuBrin, 2013 p. 25). In achieving organizational goals, a key role of followers is to collaborate with their leaders (DuBrin, 2013 p. 27). “Good leaders will always be respected”, and recognised as a huge source to the organizations future and success (Human Resource Management International Digest, 2011 p. 7). Good leadership sh...
My decision to become an electrical engineer was not a decision I took too long ago. It is something that I decided to pursue when I entered a Science, Technology, Engineering, and Math (STEM) high school. It was then that I realized how much I enjoyed working with computers and building circuits, and the fact that this career involved many subjects. Doing a lot of research to understand better what it meant to be an Electrical Engineer, I found out that in order to succeed in this career one had to know a little bit of everything. In other words, subjects such as science and math are essential to know if someone wants to be successful electrical engineer. An electrical engineer is someone who finds practical solutions to everyday problems that involve electricity, such as computers, cell phones, among other electrical equipments. In order to create a useful device one must know where to start and this is where science comes in. An electrical engineer must be able to use the scientific method, which means; one must form a procedure, test it out, and write a conclusion. These parts of the scientific method must be written clearly, so that others can recreate and test out a device or project. Math also plays a key role in this area of study, because one must be precise when creating a new device that others are going to use. For example, if one were to create a new type of cell phone one must know a lot of math in order to be able to progr...
The first telephone was invented in 1876 by Alexander Graham Bell. Telephones have increased their capabilities since they were invented. Today’s phone are portable, digital, small, and can be used for emailing or texting. The first gasoline-powered American automobile was created in 1893. Automobiles gave people personal transportation and freedom. The incandescent light bulb, patented by Thomas Edison, is used to give homes, buildings, streets, cars, and a number of other things, light. Light bulbs were revolutionary because people could use them in the dark without having to light candles or an oil lamp. Technology has evolved since industrialization, but it has been providing freedom and convenience to people for many
As a graduate student, I will undertake research and coursework in Electrical Engineering to enhance my competencies in this field. I intend to complete my master's degree in order to pursue my doctorate. The research that I am most interested in pursuing at Northeastern University surrounds the optical properties of MEMS devices, and the development of substrate-based fast electro-optical interfaces. My interest in this area stems from my undergraduate study in MEMs development for tri-axial accelerometers.
Edison is most famous for the development of the first electric light bulb. Like I said Edison was born into a time where America wasn’t very developed. He was born, and electricity had not been developed. But thanks to Edison when he had passed away on October 18, 1931 whole cities were lit up in electricity. For electricity, much of the credit goes to Edison.
As an engineering student, design, develop and test electrical equipments is the major purpose of all time. In other words, electrical engineer is concerned with using electricity to transmit electric power. In electrical engineering, there are extensive subfields such as power engineering, control system and signal processing. It is also worth to point out the difference between electrical engineering and electronic engineering. According to the research, electronic engineering is a major that deal with the electronic system such as computers and radar, to be more specific, electronic engineers are concerned with using electricity to process information.
Thomas Alva Edison is a very well-known American inventor. He invented about 1093 devices that influenced us greatly, such as light bulb, microphone, telephone receiver, universal stock ticker, phonograph, kinetoscope (used to view moving pictures), storage battery, electric pen, and mimeograph. Edison also improved many other existing devices as well. In the period from 1878 to 1880, Thomas Edison began serious research into developing a practical incandescent lamp. Edison and his associates worked on at least three thousand different theories to develop an efficient incandescent lamp. In 1878, Edison built his first high resistance incandescent electric light. Incandescent lamps make light by using electricity to heat a thin strip of material (called a filament) until it gets hot enough to glow. Many inventors had tried to perfect incandescent lamps to "sub-divide" electric light or make it smaller and weaker than it was in the existing arc lamps, which were too bright to be used for small spaces such as the rooms of a house.Edison's lamp would consist of a filament ho...
In 1831, using his "induction ring", Faraday made one of his greatest discoveries - electromagnetic induction: the "induction" or generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. The induction ring was the first electric transformer. In a second series of experiments in September he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer.
