Inventory date 1912. This electroscope signals the presence of electric charges both if charged by contact or if it undergoes electrostatic induction. It has got several didactic purposes especially in qualitative electrostatic experiments. It is also used to recognize the type of charge. Its functioning is based on the superposition of two &hellip; Leggi tutto \"\"","thumbnail_url":"https:\/\/www.istitutomontani.edu.it\/museovirtuale\/wp-content\/uploads\/2017\/11\/1DSCFBFP0507.jpg"}
