Chapter 20: #63

Throughout the 17th and 18th centuries, many breakthrough inventions were created in the field of electricity. One of these inventions was the Leyden Jar. It was constructed by taking a jar. The scientist would then coat the inside in foil and do the same for the outside of the jar. They would then connect an electrode to the inside foil in order to conduct electricity. The jar works by charging the electrode with a generator. The charge then moves into the foil. Another popular invention was the Wimshurst Machine. It was built by putting two discs spinning the opposite way. their would then be a spark gap between two metal spheres. The machine was poweered mechanically, not electrically. when the machine was cranked, it would make a spark between the two spheres.
