The need for electrical engineers was not felt until some 40 years later, upon the invention of the telephone (1876) by Alexander Graham Bell and of the incandescent lamp (1878) by Thomas A. The first practical application of electricity was the telegraph, invented by Samuel F.B.Ampere (Amp), a unit of electric current named after André-Marie Ampère (1775-1836), French mathematician and physicist, is considered the father of electrodynamics.In his honor, a unit of electric power was named "Watts". In 1769 James Watt, a Scottish Engineer transformed the limited use steam engine into a mega power source and radically transformed the world from an agricultural society into an industrial one.He created a battery out of stacks of zinc and copper, with weak acids in between each layer. In 1779 Alessandro Volta invented the first source of continuous electric current in his experiments with non-static electricity. This saves many buildings from burning down. From this experiment, Franklin invented the lightning rod, which attracts lightning and draws it into the ground. When a bolt of lightning hit the kite, a spark of electricity flew from the key. In 1752, during a dangerous electrical storm, Benjamin Franklin flew a kite that had a metal key at the bottom of the string. ![]() Thales of Miletus a Greek in 600 AD wrote of static electricity that attracted pieces of straw and hair to rubbed rods of amber.Electricity was never invented: its properties were discovered, examined, and explained.The infrastructure should be efficient, flexible to expand, economical to maintain and operate. Modern society requires smart, simple, safe, reliable, and economical electric power infrastructure for social, political, and economic activities. Without electricity, our way of life comes to a grinding halt. Just as water is necessary for survival, electricity is indispensable in daily life. ![]() From generators in a dam to fields of solar panels to the transmission lines that cross the country, experts in power tend to work on large-scale projects.During the last century and a half, electricity has evolved from a scientific curiosity, to a luxury for wealthy people and to a daily necessity in the developed and developing world.
