Electricity, a Versatile Energy
Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well- know effects such as lightning, static electricity, electro magnetic induction and the flow of electrical current. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.

Electrical phenomena have been studied since antiquity, though advances in the science were not made until the seventeenth and eighteenth centuries. Practical applications for electricity however remained few, and it would not be until the late nineteenth century that engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society. Electricity's extraordinary versatility as a means of providing energy means it can be put to an almost limitless set of applications which includetransport, heating, lighting, communications, and computation. Electrical power is the backbone of modern industrial society.

HYPOTHESIS

Benjamin Franklin carried on experiments with the Leyden jar, made an electrical battery, killed a fowl and roasted it upon a spit turned by electricity, sent a current through water to ignite alcohol, ignited gunpowder, and charged glasses of wine so that the drinkers received shocks.
More important, perhaps, he began to develop the theory of the identity of lightning and electricity, and the possibility of protecting buildings by iron rods. Using an iron rod he brought down electricity into his house, and studied its effect upon bells, he concluded that clouds were generally negatively electrified. In June of 1752, he performed his famous kite experiment, drawing down electricity from the clouds and charging a Leyden jar from the key at the end of the string.
Benjamin Franklin's letters to Peter Collinson were read before the Royal Society which Collinson belonged to but were

    He invented many things such as a lighting rod and discovered electricity(Franklin 215). In 1750, he did the experiment of flying a kite in the storm to prove lighting is electricity. In 1752, he used iron rod instead of a kite and extracted electrical sparks from a cloud. On June, he conducted the famous kite experiment in Philadelphia. this experiment was dangerous and fatal, in his writing, he indicated that he was aware of the dangers, he insisted to test the hypothesis out( ).…

    As a child, Benjamin Franklin was fascinated about lighting. Many years later, he had a theory. He believed that lightning could be a powerful source of energy. To test his theory, he flew his kite with a key attached to it hoping to harness the power of electricity. His theory was proven, and that is why electricity exists today.…

    Before Franklin started his scientific experimentation, it was thought that electricity consisted of two opposing forces. Franklin showed that electricity consisted of a "common element" which he named "electric fire." Further, electricity was "fluid" like a liquid. It passed from one body to another — however it was never destroyed. In a letter to Peter Collinson, Franklin wrote that the "fire only circulates. Hence have arisen some new items among us. We say B (and other Bodies alike circumstanced) are electricised positively; A negatively; Or rather B is electricised plus and A minus ... These terms we may use till philosophers give us better."…

    One of Franklin’s most used inventions is the lightning rod. Franklin studied electricity in a small laboratory. He assumed lightning was electricity he but wanted to prove it. “On a stormy night in 1752, he conducted a life threatening experiment to demonstrate that lightning is the result of electrical buildup. He constructed a kite that carried a metal spike and flew it into the thunderstorm” (Bhunoo 201). Franklin reeled his kite back in to study it. He was trying to get the lightning to strike the key and see if his theory was correct. “Franklin noticed that it sparked as he brought his knuckles close to it” (Bhunoo 201). As the lightning sparked he understood that it was electricity. Even though some people credit Franklin with the invention of electricity, electricity was in existence long before he was born.…

    In 1751, Peter Collinson, President of the Royal Society, arranged for the publication of a series of letters from Benjamin Franklin, 1747 to 1750, describing his experiments on electricity. Franklin demonstrated his new theory of positive and negative charges, suggested the electrical nature of lightning, and proposed a tall, grounded rod as a protection against lightning. These experiments established Franklin's reputation as a scientist, and in 1753 he received the Copley Medal of the Royal Society for his contributions to the knowledge of lightning and electricity.…
