Electricity and its impact on life By: Josh Fey and Ivan Zarkov
The discovery of electricity • Over 2000 years ago the Greeks found that if you rub an amber with fur it could attract light weight objects. • Other experiments have concluded the same result. In the 17th century Otto Van Guericke conducted an experiment where he made a large ball of sulfur, rubbed it, and then it would spark and attract small objects.
Other conformation experiments • Benjamin Franklin saw the connection between all the experiments. • He thought that the sparks coming off Guericke’s ball were the same as lightning in a storm • After some testing he set out and conducted the experiment we all know. • He took a kite attached a key and when lighting hit he knew it was the same because the key was of the same material that Guericke used to make his spark.
The start of “Batteries” • In 1800, Italian-born physicist Alessandro Volta constructed the voltaic pile, later known as the electric battery. • The first device to produce a steady electric current. • Volta discovered that certain chemical reactions could produce electricity. • Volta created the first transmission of electricity by linking positively-charged and negatively-charged connectors and driving an electrical charge through them. The start to making what is now called batteries.
Effect of discovering how to harness electricity • In 1831 electricity became viable to the people for use in inventions. • Michael Faraday an English scientist created the first dynamo. • A dynamo is a generator that could keep a steady electrical flow. • Thomas Edison followed Faraday’s work and made an electrical generator capable of making larger currents then Volta’s cells.
Thomas Edison’s life • Thomas Alva Edison born on February 11, 1847. • His family was average and they lived in Milan, Ohio next to Odessa Russia it was the biggest wheat shipping port in the world. • In 1854 his whole family moved to Port Huron, Michigan.
Thomas’s Business's • At age 12 he started his first business selling candy and newspaper on the local railroad. • At age 14 he started to write his own newspaper the “Dailey Herald”. • Shortly after printing he already had 300 regular customers.
Edison’s Savings • Making about 10$ a day he had more than enough to support himself he was able to use the extra to build his very own chemistry lab. • His mother eventually made him move it out of her basement due to the odors and smoke from the chemicals he used in his experiments.
Later Chemistry Lab • He then moved his important supplies to his locker on the train. • One day the train lurched to a stop causing one of the tubes of phosphorus to fall to the ground igniting the whole back car to go up in flames. • The conductor was so mad he gave time a very hard blow to the head and made him sell his newspaper along stations of the track.
First Invention • At age 16 after working with many telegraphs he invented his first invention. • He called it the “Automatic Repeater”. • It was able to take a telegraph message and repeat it as many times as wanted. • He never patented this invention though.
Heading Home • In 1868 he returned home to find his family in horrible condition. • His mother was very sick and almost at death. • Making matters worse the bank was about to foreclose on his house.
The Need for Money • After seeing his family Thomas set out to make some serious money. • He was offered a job in Boston which was said to be “The hub of the scientific, educational, and cultural universe at this time...."
Edison’s First Patent Invention • When he introduced his invention which was a electronic vote recorder. • He introduced his invention to market it to the members of the Massachusetts Legislature. • They thought it would disrupt the flow of the candidates and there campaigns.
In Need of a Job • Edison now living in the “Big Apple”. • He was offered a job from a stock ticketing company. • Earlier that week he had save that company by fixing a broken machine.
Back to Inventing • At age 29 he started working on a carbon transmitter. • Which was suppose to make the new telephone a lot more clear from longer distances. • In 1877 he succeeded in making the first phonograph • After all his work someone had beaten him to patenting the invention.
Introducing the Light Bulb • In 1879 he decided to one-up on his competition by inventing the first incandescent electric light bulb. • It took him longer to find a material for his filament than it did to make the light bulb. • He finally discovered carbonized cotton thread would hold an orange looking glow.
The Light Bulb • By 1880 he had made a light bulb that could hold a light 1500 hours and had quite a bright glow. • Now as we all know the light bulb is used in almost every household in the world and in many appliances including lamps and several children's toys.
How it Changed History • In 2003, there was a blackout due to electrical power loss for one summer day. Although it lasted for only one day it helped people realize the importance of the light. People were forced into using candles and flashlights.
Importance's of the light bulb • Additionally, light bulbs replaced torches for light which prevented house fires and created a safer environment. • It allowed people to wake up earlier and go to bed later, leading to more productive time in the day. • It lead is used in many present day inventions such as the head lights of cars.
