Gold Leaf Electroscope 3D model by vishnu (@vishnu
A goldleaf electroscope is a simple device which is used to identify the electric charge present in a body.Their operation is based on the principle of like sign charge repulsion. Two sheets or leaves, cut longer than they are wide and made of very thin, electrically conductive material, are hung adjacent and virtually in contact with each other. The leaves are ordinarily made of material

Gold Leaf an overview ScienceDirect Topics
Charge electroscopes (such as goldleaf electroscopes, or the aluminumfoil electroscope of Figure 1.25) and charge electrometers are devices for measuring the charge on an object, the electrometer being quantitative. They use the repulsive force between like charges. Figure 2.4 depicts an experiment to determine how much electricity can be produced by rubbing.

Chapter One ELECTRIC CHARGES AND FIELDS
A simple apparatus to detect charge on a body is the goldleaf electroscope [Fig. 1.2(a)]. It consists of a vertical metal rod housed in a box, with two thin gold leaves attached to its bottom end. When a charged object touches the metal knob at the top of the rod, charge flows on to the leaves and they diverge.
