Transcript of History of the Lightbulb

history of the lightbulb! Naasik Syed the idea Sometime in 1809, an English chemist named Humpherey Davey came up with the idea of using electricity to produce light rather than oil, coal and other things. Humphrey used two strips of charcoal and a high power battery to make the first arc lamp. The electric current going through the charcoal produced a harsh incandescent light. the second attempt In 1820, the first known attempt to make a light was made. bulb Warren De la Rue made that fist attempt.

"Great Scientists: Thomas Eddison A Life Story" By Mary Joseph. Published by New Dawn Press Rising Sun. inc Slough, Berkshire He put a platinum coil in a tube with no air in it and conducted an electric current through the coil. Here is a picture of the lightbulb that Warren made Allthough the idea worked, it could not be produced, as the platinum was too expensive. the boy named edison As a boy, young Thomas Alva Edison was very inquinsitive. Once, he was curious about how chickens hatch eggs. So as a four year old, he sat down on some eggs and tried to hatch them. When young Edison was seven, his parents moved to Port Huron, Michigan. In school, Edison's teacher was very mean, and didn't like the children asking questions. The teacher often took a walking stick and hit Edison's back with it. Edison's mother brought him home and started to educate him from home instead. thank you for watching! He was very eager to mix chemicals, liquids, and powders to see what happened. When Thomas was 12, he got a job as a "candy butcher" on a train. He would sell newspapers and candy while yelling, "Newspaper! Candy! Newspaper! Candy! Newspaper! Candy!" He gave all his earnings to his parents. They knew how much their son liked to experiment with chemicals, so they increased his pocket money. Eddison discovered that the car at the end of the train was empty, so he used it as a lab for his experiments. Thomas was kicked out of his job when one of his chemicals caught fire while the train was arriving at a station. The guard hurt Thomas on the ear after everyone was evacuated. When he was fifteen, Thomas rescued a 3 year old child from getting run over by a train. The greatful father of the child, James MacKenzie, taught Thomas telegraphy. the new light bulb Thomas worked with his team endlessly to invent a new, improved light bulb. He worked day and night to make it. He used thousands of different fillaments to see which one would glow well and be long lasting. Finally, one day, he was fiddling with his coat button when, suddenly, it fell off. "This is what I'll use for the fillament!" He gasped. He put the thread in a nickel mold in a furnace for five hours to turn it into carbon. He and his assistants passed electricity through the thread. They watched as the thread burned for 45 hours. Within a year, he had invented a bulbs that burned 100, and then 500 hours each. When the news reported about it, they called Thomas Edison "The Wizard of Menlo Park" because he lived in Menlo Park. This is what a bulb looked like at the time
