ELECTRICAL ENGINEERING

1. HISTORY:

1.1 19th CENTURY:

A search of Michael Faraday formed the basis for electric vehicle technology.

In the 19th century, began to accelerate research on the subject. In 1827 breakthrough Georg Simon Ohm, who in this century Michael Faraday, the relationship between electric current and potential difference in the director, the search for electromagnetic induction in 1831, the including the amount of work, and in 1873, James Clerk Maxwell, published the integrated management theory electricity and magnetism.

Starting in the 1830's, Telegraph made to apply power. At the end of the 19th century, the world had been forever changed by the inventions made through 18th century.

The practical applications in such fields, and the growing need for renewal of the standard unit of measurement. The units volts, the Ampere, Coulomb, ohm, farad, and led to international standards to Henry. These standards have been published in the international conference in Chicago(1893)on the basis of modern future standardization in different industries, and value in many countries quickly recognized in the appropriate legislation.

During the year, the study of electricity was largely considered to be sub-field of physics. That's because the technology was Electro electrical in nature.In 1882 TECHNICIAN Darmsdatd .
University established the Electrical Engineering degree program in electrical engineering world under Professor Charles Cross was started at the Department of Physics, Massachusetts Institute of Technology (MIT) First Division, while this Cornell University created the world's first electrical engineering graduates in 1885. Cornell Sibley College with courses in electrical engineering and mechanical engineering mechanic Arts was first taught in 1883. In 1885, President Andrew Dickson White, established the Department of Electrical Engineering in the United States. In the same year, the University College London founded the first chair of electrical engineering in the United States.Professor Mendell P. Weinbach at University of missouri soon followed suit by establishing the electrical engineering department in 1886. Afterwards,universities and institutions of technology gradually started to offer electrical engineering programs to their students all over the world.

Oliver Heaviside, theoretical models developed for electric circuits.

Using electrical engineering increased dramatically over the last few decades. 59 customers Manhattan Island in New York City - just change current (DC) . In 1882, Thomas Edison, the world's first power beyond 110 volt network. In 1884, allowing for more efficient electricity production Sir Charles Parsons invented the steam turbine. Károly called Zipernowsky, Otto the Bláthy and Miksa Deri (after ZBD transformers), the Lucien Gaulard, moving from rapid development of power more efficiently over long distances through transformers used in the 1880s and 1890s by the Transformer design with the ability to display, as Dixon Gibbs and William Stanley, Jr. .. Induction motors including AC motor was invented by practical design and develop more independent of Galileo Ferrari and Nikola Tesla and Charles Eugene Lancelot Dolivo-Dobrovolsky Mikhail in the three-level pilot form with Brown. Charles Steinmetz and Oliver Heaviside theoretical contribution to the foundation is in engineering changes.With the support of AC system is taken as AC Outbreaks in the United States has been one of George Westinghouse war of currents between Thomas Edison departed overall quality AC, DC power systems support.

1.2 MORE INNOVATIVE DEVELOPMENT:

Galileo Marconi long known for his pioneering work on radio transmission

During the development of radio, many scientists and inventors contributed to radio technology and electronics manufacturing. In the 1850's, James Clerk Maxwell work, the possibility of invisible air waves (the "radio waves was shown compared to different electromagnetic radiation, including" named). In classical physics experiments of 1888, Heinrich Hertz confirmed Maxwell's theory of radio waves with a spark gap transmitter, distributors, and by using simple electronics. Other physics used in the development of tools to find them with new impulses and they move. In 1895, Guglielmo Marconi wireless telegraphic transmission systems and commercial approach to change known methods to detect the "Hertazian waves" as a goal, start working. In the beginning, he wireless signals a distance of half a mile. In December 1901, he sent wireless waves were not affected by the curvature of the earth. Marconi after distribution Poldhu, back, and Atlantic wireless signal between St. John, Newfoundland, 2,100 miles (3,400 kilometers) away.

In 1897, Karl Ferdinand names into the cathode ray tube introduced as oscilloscope, part of a major technology for electronic television. John Fleming in 1904. Two years later the first radio tube, the diode, think, Robert von Lieben and Lee De Forest independently developed the amplifier tube, called the triode.

In 1920, Albert Hull developed the magnetron Percy ultimately leads to the development of the microwave oven in 1946 by Spencer shows progress. In 1934, the British military radar (which also uses the magnetron) Under Dr. Wimperis first radar station operation, was began in August 1936.Bawdsey.

In 1941, Konrad Zuse use electro mechanical parts Z3, the world's first fully functional and programmable computer. 1943 was designed by Tommy Flowers and Colossus, the world's first fully functional electronic, digital and computer programming. In 1946, John Presper Eckert and John Mauchly of ENIAC (Electronic Numerical Integrator and where to start from the computer), computer. Engineers Apollo program, which allowed fully to the pursuit of new technology and new goals, including landing astronauts on the moon in the arithmetic result of the performance of these devices.

1.3 SOLID STATE TRANSISTORS:

Although the strategy of the movement in 1947 by William B. Shockley, John Bardeen, and Bell Telephone laboratories Walter Brattain by opening the door to free most prescriptive devices in 1959 and Jack Integrated development round in 1958 and Kilby by Robert Noyce. Starting in 1968, Ted Hoff and a personal computer in the tent, a team in the first commercial microprocessor Intel Corporation invented. The four-bit Intel 4004 processor was released in 1971, but in 1973 the Intel 8080, eight-bit processor, the first personal computer, the 8800 Altar, as possible.
