Thomas Edison And Electricity
Rightly called the Father of Electricity, Thomas Alva Edison was born to Sam and Nancy on February 11, 1847, in Milan, Ohio. The light bulb and electricity was one of his major inventions among thousand others. Born in a poor family, Edison had hard times earning his living. But ‘fortune favors those who favor themselves’ was true in case of Edison. |

Edison worked for a company and managed to earn a good amount of money and decided to set up a lab at New Jersey in 1876. He began a series of experiments to invent the light bulb for indoor use. His aim was to make a durable filament which would burn and produce bright light. Edison tried different metals like platinum wire, refractory metals and even human hair before he finally invented a better filament in carbonized strips of bamboo. Later in 1905, came the metalized carbon filament and finally the invention of tantalum or tungsten filament took place.
Now a constant electric supply was needed to light up these indoor bulbs. Through the electric distribution system, Edison provided the supply of electricity for three thousand lamps. For this, Edison developed a unique dynamo, the largest ever made up to that time. The dynamo and the central power station helped the electric motor to gain momentum which was needed to produce the electricity. First, the dynamo convert the mechanical energy into electric energy and the motor further convert it back from electric to mechanical energy.
It was not less than a wonder for Holborn Viaduct, London, in 1882 when the DC supply system provided electricity supplies to street lamps. Several private dwellings within a short distance of the station also got constant power supply. On January 19, 1883, the first standardized incandescent electric lighting system employing overhead wires began its service in Roselle, New Jersey.
