There are multiple advances in the electrical engineering which have lightened, informed and connected the world but electrical engineering can be traced back to long before Thomas Edison.
There are many ways in which electrical engineering has been shaping the society for thousands of years.
Dynamo: The crude electric generator was invented by the Michael Faraday in 1831 and it is also known as electric dynamo. Through this the use of electricity has made possible for industrial purpose. This electric dynamo by the Faraday was able to generate stable eclectic current which was a big issue by then. It enabled the invention of other conversion devices powered by electricity.
Light Bulb: This light bulb is invented by the Thomas Edison, an American and a British scientist Joseph Swan in 1882. There was development of incandescent bulbs in their respective nations. In 1882, there was a further development of light bulb by Edison by relying on their previous direct current systems in order to illuminate the first electric street lamp.
Motors: By the discovery of the alternating currents by Nikola Tulsa in 1887, the Faraday’s current system was improved. Nikola has also done the discovery of polyphase distribution system which was very useful in transmission of power to the electric AC motors. This discovery got the attention of many researchers.
Television: This is the most famous and important invention in household electronic gadgets by Philo Farnsworth in 1928. He also made the first public demonstration of the electric television this year. Through this, many countries made televised broadcasts in the early 1930.
Radiolocation and Radars: There was a risk of aerial attacks by the First World War. Nations were more worried about it and took necessary steps to develop technologies which would find the aerial attacks. With the help of radar technology, nations would simulate the aerial attacks. But these technologies become most important priority at the time of Second World War.
Computers: The world’s first programmable computer was developed by the Konrad Zuse in 1941 and dubbed the Z3. These developments were essential as there was also the development of other land breaking technologies which also includes NASA Apollo mission.
Transistors and Microprocessors: The compact devices always trust on these transistors in order to perform. These transistors were brought by William B Shockley, John Bardeen, and Walter Brattain in 1947. The invention of the transistors led to the development of the integrated circuits by Jack Kilby in 1959.
