Cylindrical Gold-Leaf Electroscope (early 1900s) |
|
Standard gold leaf electroscope (ca. 13" tall) for qualitative demonstrations of electrostatic phenomena. In this example, the two leaves appear to be aluminum rather than gold. The two leaves are separated by a vertical plate (at the bottom of the lead-in) which prevents them from touching each other. This feature permits the electroscope to be operated with either one or two leaves. The body is made of brass with a black painted interior, the Volta disk on top is steel, the insulator for the lead-in is amber and the supporting post is glass. In general, an electrophorus would be used to transfer a charge to the horizontal disk (Volta plate) on the top.
