changed the course of history. Franklin did many amazing things in his life. He was an avid inventor‚ a scientist‚ and a leader. He invented many things such as the Franklin stove‚ and bifocals. As a scientist‚ he discovered that lightning conducts electricity‚ and as a leader he helped draft the declaration of independence and was a general in the French and Indian war. Benjamin franklin was many things‚ including an inventor‚ his inventions helped better everyone’s

used today‚ the contrivance used to compose the telegraph guided the development of telephones‚ television‚ and many other electronic based devices. Telegrams were sent to communicate transversely throughout the world and forever changed the way electricity was used. Before this invention‚ a simple letter or semaphore would have to suffice. In the 1830’s‚ the telegraph was first invented. The telegraph had high expectations as it was invented to communicate to help railroad signaling in Britain. (Morse

prisoners. Edison tried to popularise the term “Westinghoused” as electrocution. In 1887‚ a prize of $US20 000 was offered to the company that could design and construct a system to generate hydro-electric power at Niagara Falls and transmit the electricity to the city of Buffalo (35km away from the falls). Westinghouse won the competition with the proposal of AC. The reason for AC winning is the ability to transmit power over long distances. By the late 1890s AC’s advantages was clear and large

electrophorus; a device that produced static electricity. In 1776-77 he devoted his time to chemistry‚ studying atmospheric electricity‚ and devising experiments such as the ignition of gases by an electric spark in a closed vessel. In 1779 he became professor of physics at the University of Pavia‚ a chair he occupied for 25 years. By the 1800 he had developed the so-called voltaic pile‚ the first invention of the electric battery; it produced a steady stream of electricity. Volta also studied what we now call

Electrical Safety in the Perioperative Environment There are numerous ways electricity is employed in the operating room environment‚ such as X-ray machines‚ electrosurgical units‚ monitors‚ surgical table and lights‚ endoscopic cameras and monitors‚ lasers‚ and robotics. Each piece of machinery comes with certain safety precautions when using them in the perioperative environment. Since almost all injuries in the OR result in human error‚ it is important to follow these precautions to ensure

Background of the Study Electricity plays very important role in the lives of people to make their work become easier and faster. It also provides productivity to our community. Industries use it to run motors efficiently. Several years ago‚ REINA which composed of 3 municipalities is simply a single town‚ which is Infanta. There was no supply of electric current in the town. Some public and private sector uses generator and some devices that generate electricity for the operation of different

Michael Faraday was the third son of a London blacksmith. He became a self- taught scientist whose greatest discoveries concerned electricity. In 1831‚ Faraday proved that magnets can be used to produce an electric current. This discovery enabled him to build an electric generator. It was a forerunner of the giant dynamos that keep the modern world supplied with power. Faraday was born on September 22‚ 1791‚ in Newington‚ England. When he was five‚ his family moved to London

sources of electricity such as primary batteries and the power grid‚ mechanically powered flashlights. Such devices contain electrical generators or an induction system to recharge their batteries. Separate crank-operated generators are now available to recharge battery-powered portable electronic devices such as cell phones. Others‚ such as mechanically powered flashlights‚ have the generator integrated within the device itself. A promising alternative to rechargeable batteries for electricity storage

compounds conduct electricity and covalent compounds do not. Once ready the unknown solutions a certain amount of them was placed in four labeled beakers. The conductivity of each was measured with an apparatus containing a light bulb which was plugged in a 110 volt outlet. The ionic compound solutions A C results were bright light‚ D solution result was dim light. Solution B was a covalent compound which result was no light. The results showed which solutions conducted electricity. Introduction:
