To dispel another myth, Franklin’s kite was not struck by lightning. If it had been, he probably would have been electrocuted, experts say. Instead, the kite picked up the ambient electrical charge from the storm. Here’s how the experiment worked: Franklin constructed a simple kite and attached a wire to the top of it to act as a lightning rod.

Speculations of Jean-Antoine Nollet had led to the issue of the electrical nature of lightning being posed as a prize question at Bordeaux in 1749. In 1750, it was the subject of public discussion in France, with a dissertation of Denis Barberet receiving a prize in Bordeaux; Barberet proposed a cause in line with the triboelectric effect. The same...
In 1752, Franklin proposed an experiment with conductive rods to attract lightning to a leyden jar, an early form of capacitor. Such an experiment was carried out in May 1752 at Marly-la-Ville in northern France by Thomas-François Dalibard. An attempt to replicate the experiment killed Georg Wilhelm Richmann in Saint Petersburg in August 1753; he w...
Franklin's kite experiment was performed in Philadelphia in June 1752, according to the account by Priestley. Franklin described the experiment in the Pennsylvania Gazette in October 19, 1752, without mentioning that he himself had performed it. This account was read to the Royal Society on December 21 and printed as such in the Philosophical Trans...
The experiment proved Franklin's theory that lightning is electricity and led to his invention of the lightning rod. Benjamin Franklin, with his son William, conducts his famous lightning experiment—flying a kite during a thunderstorm with a key attached to the string—in 1752.
Franklin is probably most famous for his kite experiment. As the story goes, he and his son flew a silk kite on a long cord when the sky was full of black clouds. A metal rod was tied to the kite. An iron key was attached to the end of the cord.
Benjamin Franklin Drawing Electricity from the Sky, an artistic rendition of Franklin's kite experiment painted by Benjamin West, c. 1816. The kite experiment is a scientific experiment in which a kite with a pointed conductive wire attached to its apex is flown near thunder clouds to collect static electricity from the air and ...
14 de jun. de 2018 · His famous kite-and-key experiment in 1752 demonstrated that lighting was electricity. He invented the lightning rod. Some of the terms he coined are still used today, such as battery, charge, and electrify.
Benjamin Franklin experimented with electricity by flying a kite during a thunderstorm.
