خلاصہ

تفصیل Drawing of a gold-leaf electroscope from around 1900. The grounded metal strips flanking the leaves improve sensitivity and are a protective device. If the delicate leaves receive an excessive charge, they will touch the strips and discharge, rather than tearing. Alterations: removed caption, removed attached collector rod since it was irrelevant and confusing.
