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 ...
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 ...
Voltages used for electric power transmission increased throughout the 20th century. [50] The first "high voltage" AC power station, rated 4-MW 10-kV 85-Hz, was put into service in 1889 by Sebastian Ziani de Ferranti at Deptford, London. [33] The first electric power transmission line in North America operated at 4000 V.
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 ...
