### GCSE PHYSICS Electrostatic Charge What is a Gold Leaf

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

### Electroscope JavaLab

Sep 24, 2019· 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 foil’s free electrons are attracted to the metal plate, and a positive charge is induced in the metal foil.

### 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.
