Gold-Leaf Electroscope is one of the instruments used for testing positive and negative charges. It consisted of a metal rod, A to which gold leaves, L were attached See image below. The rod was fitted with a circular disc or cap B and was translated with a plug P from a metal case C which screened L from outside influences other than those bought near to B.Online Chat
A Gold leaf electroscope is used in electrostatics to show the magnitude and polarity of charged entities. These are best stored in a warm dry environment as the charge is easily dissipated in moist conditions. It is also used with a zinc plate to illustrate the photo-electric effect.See Photoelectric effectOnline Chat
The gold leaf electroscope has a very very thin piece of gold foil called gold leaf fixed at the top to a piece of copper. The copper has a large round top, called the cap. The whole thing is put inside a glass case, to stop air blowing the delicate gold leaf around. The piece of copper goes through insulation in the top of the glass case, so that any charge on the gold leaf cannot escape.Online Chat
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.Online Chat
GOLD LEAF ELECTROSCOPE It is an instrument for detecting and measuring static electricity or voltage. A metal disc is connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate. The whole of this part of the electroscope is insulated from the body of the instrument.Online Chat

1 To charge by induction a perspex rod must be charged positively, via contact with a cloth removing negative charge leaving excess positive charge on rod. 2 Then the positively charged rod is brought near the zinc plate at the top of Gold leaf electroscope GLEOnline Chat
Produced by the National STEM Learning Centre and the Institute of Physics, this video demonstrates how to use a gold-leaf electroscope, zinc plate and an ultraviolet light source. The zinc plate is placed onto the top of the electroscope and it is given a negative charge.Online Chat
Electroscope. Using an electroscope, you can determine whether an object is charged or the polarity of the charge. When the charged body is close to the metal plate, the metal foils free electrons are attracted to the metal plate, and a positive charge is induced in the metal foil.Online Chat
A gold leaf electroscope measures potential difference between the leaf and the base or earth. The leaf rises because it is repelled by the stem support. The leaf and its support have the same type of charge.Online Chat

A gold-leaf type electroscope is a device used to detect the presence of electric charge on a body and its relative amount. The electroscope is usually constructed with a metal plate or sphere at the top of a metal post electrode with thin foil leaves e.g., gold hanging from the bottom of the post.Online Chat
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. Bennets electroscope consisted of a pair of very thin, narrow leaves of gold hung from a conducting rod surrounded by glass housing.Online Chat
