1.4: Experiments with a Gold-leaf Electroscope - Physics ...

The gold leaf collapses, though by this time the electroscope bears a positive charge, because it has lost some electrons through your body. Now remove the plastic rod. The gold leaf diverges again. By means of the negatively charged plastic rod and some deft work with your finger, you have induced a positive charge on the electroscope.

1927: NBS gold leaf electroscope | NIST

The NBS Standard Gold Leaf Electroscope. The ionization chamber consists of a 10 cm-cube free-air volume, with walls made of 1 cm thick lead sheet with ½ cm thick aluminum lining. A gold leaf is suspended near the center of the chamber and a quartz fiber, 10 µm in diameter, at the free end of the leaf provides a fine scale for optical ...

gold-leaf electroscope - David Darling

A gold-leaf electroscope is an instrument used (mainly historically) for the measurement of electric charge or potential, based on one or two fine gold foils suspended vertically and free to deflect under electrostatic repulsion when an electric charge was applied (seeFigure 1). Although never very accurate, the instruments could sometimes detect as little as 10-14 coulomb and were used to ...

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.
