Thomas Alva Edison
Edison (1847-1931) invented over 1000 inventions. He was born in
Milan, Ohio, in the US. In 1879, he demonstrated the
first successful electric light bulb. He discovered that electricity would flow from the bulb's glowing
filament onto a metal plate inside the bulb. This is known as the 'Edison Effect'.
Nikola Tesla was also a scientist at the
same time as Thomas Alva Edison, Tesla originally came from Serbian and became an American
scientist. He also was a brilliant and very eccentric genius whose inventions enabled
our modern-day power systems and the mass communication systems we all now enjoy.
His opponent and former boss Thomas Edison, was as stated above; the inventor of the light bulb,
the phonograph and the moving picture. The two feuding geniuses competed with each other over
whose electrical system would be the best system to provide mass electrical energy to the people.
Would it be Tesla's alternating-current (AC) system? or Edison's direct-current (DC) system? Do you
know who's system is used today to provide us with mass electrical energy?
