Description |
Italiano: Tipico elettroscopio a bottiglia formato da una campana di vetro poggiante su una base in ottone e chiusa nella parte superiore da un tapppo, anch'esso metallico. Il tappo è forato nel centro e nel foro è infilata un'astina, sempre metallica, che termina in alto con una piccola sfera. L'estremità dell'asta che è situata dentro la campana portava in origine due foglioline d'oro oggi perdute Una piccola vite posizionata sul tappo permette di fissare l'asta nella posizione desiderata
