The electroscope is a device for detecting electric charge on an object.
An electroscope has a brass rod passing through a tight fitting cork in a glass bottle. A pair of thin aluminum leaves is attached to the lower end of the brass rod. To protect the aluminum 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.
When a charged rod is touched to the metal disc, the charge is transferred to the aluminum leaves and they diverge.
