Gold Leaf Electroscope 1787 MagLab

The gold leaf electroscope, like the one illustrated here, first appeared in the latter part of the 18th century. Abraham Bennet, a clergyman and man of science, first described the instrument in Philosophical Transactions in 1787. Bennet’s electroscope consisted of a pair of very thin, narrow leaves of gold hung from a conducting rod

Gold Leaf Electroscope TecHKnow Wiki

A gold leaf electroscope demonstrates potential difference between the leaf and the case (or earth). The leaf rises because it is repelled by the central electrode or stem. The leaf and the electrode have the same type of charge. There are various forms this can take but it is usual for a metal case to be used.

Experiments with a gold-leaf electroscope Physics Homework

Experiments with a gold-leaf electroscope (1) To detect the presence of charge on a body If a rod of some suitable material is charged by friction and then brought near to the cap of a gold-leaf electroscope the leaf is seen to diverge from the plate. A charge has been induced on the leaf and plate, and consequently repulsion occurs between them.
