In deed, his work and experiments resulted in several important discoveries and inventions including electricity, bifocal glasses, a usable battery and many more. Ben Franklin believed electricity could be harnessed from lightning. In 1752, he devised an experiment to test his theory. Although details of the experiment remain sketchy to this day, Franklin originally wanted to test his theory atop a spire that was to be built on a Philadelphia church.
In fact, electricity did not begin when Benjamin Franklin at when he flew his kite during a thunderstorm or when light bulbs were installed in houses all around the world. The truth is that electricity has always been around because it naturally exists in the world.his is the basis of static electricity. Over the centuries, there have been many discoveries made about electricity. We've all heard of famous people like Benjamin Franklin and Thomas Edison, but there have been many other inventors throughout history that were each a part in the development of electricity.
