In the beginning God said "Let there be light" so maybe the first profession in the world was electrical engineering. When the Greek Philosopher Thales observed that when an amber is rubbed against fur, it could attract pieces of materials like feathers, in this way he demonstrated the early discovery of the relationship between electricity and magnetism. But with such tremendous discovery electrical engineering did not flourish during that period, ancient Greeks were not too interested in experimental science since they were too busy with philosophy and metaphysics. If they discovered electricity during that time then Christopher Columbus should have used GPS when he discovered the Americas and the execution of Rizal is a trending topic in the social networking site.
The Renaissance Period - Industrial Revolution
It was not until the renaissance period that scientists gave serious attention to this electrical phenomenon. Electrical phenomenon is the direct effect of the movement of electrons --- period. Such a movement could manifest illumination, creation of magnetic field, heating and many others. Since electron is one of the fundamental blocks of matter, its effect and manifestation transcends to other forces of nature and in one way or the other it was caught by the curiosity of early scientists. For example Alesandro Volta proved that when two metals of different composition such as lead and zinc are submerged into a certain chemical, the electron will flow from lead to zinc and thus producing electricity, this is the birth of the battery. Micheal Faraday on the other, hand without the aid of mathematical equations demonstrated the law of electromagnetic induction in several ways. It was James Clark Maxwell provided mathematical explanations of the former to translate the idea. Faradays observation lead to the invention of electric motor and transformer. The birth of the new terminologies was introduced during this period such as electric pressure (voltage), electric flow (current) and resistance. It was Georg Simon Ohm who introduced the relationship between the three basic quantities of electricity and it was called the Ohm's Law. With the further development of this new discipline, they realized that electric circuit (where the electron flow) and its mathematical analysis could be as complex as possible.Few names to mention such that gave significant solution to these problems are Thevenin, Norton, Stienmitz and Siemens.
The Rise of Electrical Engineers
During the 19th and 20th century the research and discoveries made by prominent electrical pioneers were being further put into more complex and sophisticated application. By inventing machines that can be used in our home, industry, communication, transportation among others. These new bred of electrical engineers are using the same principles laid by the founders of electrical engineering to create more products and innovations. Few names to mention who made significant contribution were Thomas Edison (electrical bulb), Nikola Tesla (transformer, AC system, electric motor) and William Shockley (transistor), Heinrich Hertz (radio technology) and Alexander Graham Bell (telephone). Nowadays researchers of electrical engineering combined this discipline into other areas of science and technology to create more innovations. The areas of electrical engineering is very wide that covers power system, industrial control and instrumentation, communication, computer, electronics among others. Today the innovation of electricity is everywhere without which the current civilization is not possible.
