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 ...
He also suggested that electricity is more akin to magnetism and light than to a fluid, since it passes through glass and cloth, and can be concentrated as a spark to light up flammable materials. On 14 August 1747 he made an experiment to conduct electricity through a 6,732 foot long wire at Shooter's Hill in London. At another experiment he ...
These fake electric shocks gradually increased to levels that would have been fatal had they been real. [2] The experiments unexpectedly found that a very high proportion of subjects would fully obey the instructions, with every participant going up to 300 volts, and 65% going up to the full 450 volts.
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 ...
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 ...
Between 1747 and 1750, Franklin sent many letters to his friend Collinson in London about his experiments with the electrostatic machine and the Leyden jar, including his observations and theories on the principles of electricity. [12] These letters were collected and published in 1751 in a book entitled Experiments and Observations on Electricity.
The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator.Kelvin referred to the device as his water-dropping condenser.
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.
