What is another word for gold-leaf electroscope?
Pronunciation: [ɡˈə͡ʊldlˈiːf ɪlˌɛktɹə͡ʊskˈə͡ʊp] (IPA) 
The gold-leaf electroscope is an instrument that is used to detect and measure the presence of electric charge. It works by using a thin gold leaf that is suspended within a metal enclosure. When an electric charge is introduced, the gold leaf becomes charged as well and will then move away from the metal enclosure due to the repulsion of the like charges. There are a few synonyms for the gold-leaf electroscope, including the gold-leaf voltmeter, the electroscope meter, the electric charge detector, and the charge measuring instrument. Despite the different names, all of these devices share the common function of detecting and measuring electric charge for scientific or experimental purposes.
