Franklin invented the lightning rod based on what he learned from experiments with his electrostatic machine. [11] [40] Franklin and his associates observed that pointed objects were more effective than blunt objects at "drawing off" and "throwing off" sparks from static electricity. [12] [41] This discovery was first reported by Hopkinson. [19]

Experiments and Observations on Electricity is a treatise by Benjamin Franklin based on letters that he wrote to Peter Collinson, who communicated Franklin's ideas to the Royal Society. [ 1 ] [ 2 ] The letters were published as a book in England in 1751, and over the following years the book was reissued in four more editions containing ...
In 1746–1748, Benjamin Franklin experimented with charging Leyden jars in series, [23] and developed a system involving 11 panes of glass with thin lead plates glued on each side, and then connected together. He used the term "electrical battery" to describe his electrostatic battery in a 1749 letter about his electrical research in 1748.
An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...
The Franklin Institute is a science museum and the center of science education and research in Philadelphia, Pennsylvania. It is named after the American scientist and statesman Benjamin Franklin. It houses the Benjamin Franklin National Memorial. Founded in 1824, the Franklin Institute is one of the oldest centers of science education and ...
The name of Gordon was not always mentioned, though both inventions are fully described by him in his Versuch einer Erklarung der Electricitat (Erfurt 1745). Benjamin Franklin , who is usually credited with the latter invention, simply adopted the "German chimes" (described by Watson in his famous Sequel , 1746) to serve as an electrical ...
The Leyden jar, a device for storing electric charge, is invented by Pieter van Musschenbroek.It Is the first capacitor.; Andrew Gordon describes the "whirl", the first electrostatic reaction motor, and "electric chimes", the first instance of the application of what comes to be called electric convection, in his Versuch einer Erklarung der Electricitat.
