Everything about C F Du Fay totally explained
Charles François de Cisternay du Fay
(Paris,
14 September1698 – 1739) was a
French chemist and superintendent of the
Jardin du Roi.
He discovered the existence of two types of
electricity and named them "
vitreous" and "
resinous" (later known as positive and negative
charge respectively.) He noted the difference between
conductors and
insulators, calling them 'electrics' and 'non-electrics' for their ability to produce
contact electrification. He also discovered that alike-charged objects would repel each other and that unlike-charged objects attract.He also disproved certain misconceptions regarding electric charge, such as that of Dr.
Stephen Gray who believed that electric properties of a body depended on its colour. Du Fay's observations on electricity were reported in a paper written in December of 1733 and printed in Volume 38 of the Philosophical Transactions of the Royal Society in 1734.
