An electroscope is an apparatus to test an electric charge.
Conclusion: An electroscope has a brass rod passing through a tight fitting cork in a glass bottle. A pair of thin gold leaves are attached to the lower end of the brass rod. To protect the gold leaves from external electric charge the lower half of the bottle is lined with tin foil which is ‘earthed’ by connecting it to the table. This kind of electroscope is called a gold leaf electroscope.
Working: When a charged rod is touched to the metal disc, the charge is transferred to the gold leaves and they diverge.
