The electroscope is used for the detection of electrical charges and voltages with high sensitivity. The electroscope consists of a metal housing with a 4 mm socket for grounding purposes and glass front and rear.
The support for the pointer with pivot bearing is attached electrically insulated to the top plate. The pointer is suspended asymmetrically and so its weight delivers the restoring moment.
At the upper part of the device there is a 4 mm socket which is connected to the pointer support for mounting a sphere and a capacitor plate. A scale allows reading of the electrical charge. For demonstration experiments the electroscope is suitable for shadow projection.
