The experiment was first proposed in 1752 by Benjamin Franklin, who reportedly conducted the experiment with the assistance of his son William. The experiment's purpose was to investigate the nature of lightning and electricity, which were not yet understood. Combined with further experiments on the ground, the kite experiment demonstrated that ...
The first proper lightning rod was invented by ... was invented by Benjamin Franklin in 1752 as ... the height, and the number of lightning strikes per year ...
The famous kite experiment enabled the Philadelphia group to established what had been surmised by others, that lightning was identical to the mild charge of electricity produced by the friction of the electrostatic machine. Franklin invented the lightning rod, which goes down in history as the first practical electrical invention.
Thus, the practical use of lightning rods, attributed to the inventor Benjamin Franklin, was confirmed. [17] 1752 Flexible urinary catheter. In medicine, a catheter is a tube that can be inserted into a body cavity, duct, or vessel. Catheters thereby allow drainage, injection of fluids, or access by surgical instruments.
West based his painting on a well-known experiment Franklin conducted in 1752. Franklin observed that lightning frequently destroyed homes by igniting those made of wood. Franklin was determined to prove the presence of electricity in lightning through an experiment.
On May 10, 1752, Thomas-François Dalibard of France conducted Franklin's experiment using a 40-foot-tall (12 m) iron rod instead of a kite, and he extracted electrical sparks from a cloud. On June 15, 1752, Franklin may possibly have conducted his well-known kite experiment in Philadelphia, successfully extracting sparks from a cloud.

English scientist Stephen Gray made the distinction between insulators and conductors. 1745: German physicist Ewald Georg von Kleist and Dutch scientist Pieter van Musschenbroek invented Leyden jars. 1752: American scientist Benjamin Franklin showed that lightning was electrical by flying a kite and explained how Leyden jars work. 1780
