Modern Developments in Electrical Engineering

Earlier electrical engineering was not so much popular so there was very less development work done it but as the time passed a lot of development starts in the field of electrical engineering, and now there are many electrical Engineering Jobs opportunities. Different Engineering Recruitment companies and Engineering Recruitment Agency is hiring electrical engineers. The development of radio, many scientists and inventors contributed to radio technology and electronics. Heinrich Hertz transmitted and he detected radio waves using electrical equipment. Nikola Tesla was able to detect signals from the transmissions of his New York lab at West Point in 1895 (a distance of 80.4 km / 49.95 miles). Karl Ferdinand Braun introduced the cathode ray tube as part of an oscilloscope, a crucial enabling technology for electronic television in 1897. John Fleming invented the first radio tube in 1904. Two years later, Robert von Lieben and Lee De Forest independently developed the amplifier tube, called the triode. Guglielmo Marconi furthered the art of hertzian wireless methods. Early on, he sent wireless signals over a distance of one and a half miles in 1895 and he sent wireless waves that were not affected by the curvature of the Earth. Marconi later transmitted the wireless signals across the Atlantic between Poldhu, Cornwall, and St. John's, Newfoundland, a distance of 2,100 miles (3,400 km) in December 1901. In 1920 Albert Hull developed the magnetron which would eventually lead to the development of the microwave oven in 1946 by Percy Spencer. In 1934 the British military began to make strides toward radar (which also uses the magnetron) under the direction of Dr Wimperis, culminating in the operation of the first radar station at Bawdsey in August 1936.

Konrad Zuse presented the Z3, the world's first fully functional and programmable computer in 1941 and the ENIAC (Electronic Numerical Integrator and Computer) of John Presper Eckert and John Mauchly followed, beginning the computing era in 1946. The arithmetic performance of these machines allowed the engineers to develop completely new technologies and achieve new and more objectives, including the Apollo missions and the NASA moon landing.

The invention of the transistor in 1947 by William B. Shockley, John Bardeen and Walter Brattain opened the door for more compact devices and led to the development of the integrated circuit in 1958 by Jack Kilby and independently in 1959 by Robert Noyce. Starting in 1968, Ted Hoff and a team at Intel invented the first commercial microprocessor, which presaged the personal computer.
