Document Summary
Earth is a giant magnet (explaining compass) Charles francois du fay electric materials possessed attraction and repulsion, resulting in vitreous and resinous electricity. Means of storing electric charge, made electrical studies popular and possible. Total quantity of electricity is conserved and that electricity flows from an object with an abundance of electricity to an object with a deficiency of electricity. One substance of electrical fluid whose action was transmitted at a distance. With franklin"s law of the conservation of charge and priestley"s law of attraction, the study of electricity was brought to a precise mathematical form. Three people stand on wax and charge one, and see which way charge could travel, realised that when they touched, they share a charge. Only the ratio of charge content that governed the flow of electricity. Inventors of the torsion balance which allowed for the precise experimental determination of priestley"s law of electrical attraction, now the law is called coulombs.
