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 ...
Hauksbee continued to experiment with electricity, making numerous observations and developing machines to generate and demonstrate various electrical phenomena. In 1708, Hauksbee independently discovered Charles's law of gases, which states that, for a given mass of gas at a constant pressure, the volume of the gas is proportional to its ...
Von Reichenbach did not tie Odic force into other vitalist theories. Baron von Reichenbach expounded the concept of Odic force in detail in a book-length article, Researches on Magnetism, Electricity, Heat and Light in their Relations to Vital Forces, which appeared in a special issue of a respected scientific journal, Annalen der Chemie und ...
When linked in series, the cells had sufficient power to electroplate a small token and to deliver current to acupuncture type needles for therapeutic purposes, but not enough to deliver an electric shock to MythBusters co-host Adam Savage who was instead pranked by co-hosts who hooked him up to a 10,000 volt cattle fence shock generator.

The frog galvanoscope, and other experiments with frogs, played a part in the dispute between Galvani and Alessandro Volta over the nature of electricity. The instrument is extremely sensitive and continued to be used well into the nineteenth century, even after electromechanical meters came into use.
It was used in early scientific investigations of electricity and academic demonstrations. The principle behind the battery is the injury potential created in a muscle when it is damaged, although this was not fully understood in the 18th and 19th centuries; the potential being caused incidentally due to the dissection of the frog's muscles.

T1- d527 - Fig. 267. — Expérience Dalibard - Marly. Dalibard, who at the suggestion of Georges-Louis Leclerc, Comte de Buffon, translated Franklin's Experiments and Observations on Electricity into French, performed Franklin's proposed experiment using a 40-foot-tall metal rod at Marly-la-Ville on 10 May 1752.
