Benjamin Franklin was a man of many types of work and expertise. He was a journalist, publisher, author, philanthropist, abolitionist, public servant (official), scientist, diplomat, and inventor as well! Franklin also was one of the leaders of the American Revolution, and one of the signers of the Declaration of Independence. His words are well-known and much quoted. For example, "time is money" is likely to come from him. Because he was also a publisher and owner of printing, many words can still be read people until now because he was also a lot and writing. He is also famous for its percobaanya on electricity (lightning rods). He was the first Postmaster in the United States, making "public library" first, and the first to organize the ranks of the city fire department.
Benjamin Franklin was born in Boston, Massachusetts, the 15th child of 17 brothers. His father worked as a soap and candle maker. He learned to read in a very young age and attended regular school for a year and studied under the guidance of a private teacher for a year. Franklin only attended for two years. At the age of 12 years, Franklin worked in the printing brother. When Ben (Benjamin nickname) was 15 years old, Ben scored the newspaper "New England Courant", the first newspaper that is independent from British colonization.
At the age of 17, Franklin went to Philadelphia, Pennsylvania to find a new experience in a new city. At that time he worked in a shop that sells printing machines. After several months, the governor of Pennsylvania recommends Benjamin to open a printing business newspapers in Pennsylvania and promised to help businesses Benjamin printing. Governor recommends Benjamin to go to London and buy printing supplies are required. But after Benjamin arrived in London, Benjamin realized that the governor promises to help only a dead letter, a letter of introduction from the governor was never sent to London. In London, Franklin quickly able to find a job. In 1726 Franklin was tired of staying in London, and by accident as it was a grain merchant offered him a job in Philadelphia with big commissions. For that Ben decided to return to America.
Benjamin Franklin and the kite-layangPada in 1740, electricity was a novelty. Benjamin Franklin and his friends began to investigate the phenomenon of electricity. In 1750, Benjamin was first who discovered the principles of electricity and also give positive and negative electricity. He then published his experiments to prove that lightning is actually electricity by flying a kite in a storm. In his writings, Benjamin Franklin wrote that he was aware of the dangers that can result from the experiments and offer an alternative that proves that lightning is electricity, which is then in the show by using the concept of electrical ground. Not as pictured person that Benjamin experiment done by flying a kite and wait until the kite was struck by lightning. Benjamin uses his kite just to collect electricity from storm clouds.
Experiments to electricity by Benjamin, directing him to the invention, the lightning rod. He wrote that the conductor (electric) with a sharp edge has the ability to draw an electrical charge and has a range of further withdrawals than conductors with a blunt tip. He concluded that this knowledge can be used to protect the house from lightning danger, by putting an iron bar seruncing pointy needles and anti-rust coating, which is directed to the sky, and the legs of iron, attached with wires leading to the ground. This will attract the lightning rod at electric charge cloud to the ground so that the charge is on the cloud is not enough to cause thunder and lightning.
Benjamin discoveries such as lightning rods, sunglasses, and others never patented it. In his biography, Benjamin writes: ".. the same as when we are enjoying the advantages of the invention of others, we should be happy to have the opportunity to provide service to others with our findings: for this, we must give freely and wholeheartedly. '
To commemorate Benjamin Franklin in the field of electricity, immortalized as physics unit franklin (Fr) or statcoulomb (statC) or electrostatic unit of charge (ESU). Fr is a unit of electrical charge in the centimeter-gram-second (cgs). SI system as we use, wear Coulomb force.
