Electricity

            
             Electricity is them most important invention of all time. Greeks first found around 600 BC that rubbing amber and fur together caused static electricity. For many years electricity was a mystery and many inventors experimented in order to understand more about how electricity work and how it could be used. There were many people that contributed to the invention of electricity. Among those are William Gilbert, Francis Hauksbee, Benjamin Franklin, Luigi Galvani, and more. On October 17th, 1831, Michael Faraday demonstrated that passing a magnet through a coil of wire could produce electricity. This was the documented time of invention and Faraday just happened to be the right mind in the right place at the right time. .
             There were many obstacles during the invention of electricity. Problems occurred frequently and the steps to understanding how it worked were very slow. The real key to how electricity progressed is the way the inventors fed off of each other's revelations. As one man would question something another would start to prove him wrong. This happened for many years. An example occurred in 1786 when Galvani experimented with a frog and electrical current. He found that a discharge of static made the frog's legs jerk. He claimed that the fluids in the leg supplied electricity but Alessandro Volta did not agree. Volta built the voltaic pile, an early type of battery, to prove the electrical charge came from the battery. .
             As electricity developed over the years many inventions followed. The battery followed. Volta invented an early type of battery and the current from the battery led to Ohm's Law, which related current, voltage, and resistance. Another very important invention was the actual generation of the electricity. Once scientists knew electricity existed they worked to find a way to use it. In 1819 Hans Christian Oersted discovered that a magnetic field surrounds an electric wire.
