Franklin's Electricity

Benjamin Franklin began his experiments on electricity in the 1740s and communicated his results to correspondents in Great Britain. In 1751, Franklin's letters were compiled into a book. The letters described Franklin's work on lighting strikes and lightning rods and discussed his positive & negative theory of electrical fluid.
