ORIGIN AND GROWTH OF ELECTRICITY
The history of electricity can be traced back to the eighteenth century. The first instance of sensing the phenomenon of electricity was the accidental observation of what was later found out to be neon glow by Framas Bauksbw in 1709 at the Royal Society in London. Luigi Galvani observed moving of the legs of a dead frog when touched with a metal scalpel. This also was later found to have happened due to production of electricity by chemical process. Almost at the same time, Alessandro Volta made the first form of battery. Thus a new phenomenon, the Electric current, was produced which paved the way for the historic and swift growth of Electricity Science. Andre Marie Ampere (1775 to1836) and George Simon Ohm (1787 to 1854) made notable forward leaps in this new sector of science. Later, the invention of electric bulbs, electric motors, etc, initiated the astonishing growth of Electrical Engineering.1
The industrial revolution and the consequent industrial growth were virtually the growth of electricity also. Electric drives actually drove the whole industrial world. The modern age saw the emergence of Electricity as a household helper also. Many consider the invention of Electricity and Electricity industry to be the major breakthrough after the discovery of fire.
The history of Electrical Engineering in India can be traced to as far back as 1886, when unorganized schemes for electric supply were established in various parts of the country. The first power station in India was at Darjeeling, established in 1897. Pioneers in power generation in India were the Mysore Government. A 450 kW hydroelectric project was set up in Kaveri River at Sivasamudram in 1902. This was for power supply to the gold fields at Kolar. However, commissioning of the hydroelectric project Simshapur in Karnataka can be considered the
