This article was about the history and how far we have come in electricity. In 600 BC when the Ancient Greeks discovered that rubbing fur and amber together causes something we know today as static electricity. Which was actually negative particles called electrons building up and jumping from one place to another. In 1752 a Man named Benjamin Franklin conducted an experiment using a kite, a key and a storm. His theory was that lightning and electric sparks were the same thing and he was right. The key attracted electricity from storm clouds which traveled down the kite string and gave him an electric shock. In 1800 Italian physicist Alessandro Volta created the first electrochemical battery, the Voltaic Pile. It used special chemicals that break apart and release electrons. In 1832 English scientist Michael Faraday made a better battery and later scientists like Nikola Tesla and Thomas Edison made some big electrical discoveries including the light bulb. Finally, in 1881 a town in Surrey in the UK became the first in the world to be lit with electrical light.I now understand that there are a whole bunch of different ways we can generate electricity.I also understand that we have come a long way in terms of electricity.What is the biggest electrical source in the world?
