A Gold Leaf Electroscope

The gold leaf electroscope like the one illustrated here first appeared in the latter part of the 18th century.

A gold leaf electroscope.

It consists of a metal rod which is fitted in an insulating box. Electroscope it is a device that is used for detecting whether an object is charged or uncharged. The whole of this part of the electroscope is insulated from the body of the instrument. It is a simple device to detect the presence of charge on any body.

This instrument is used for the detection of charge and measuring static electricity. The mouth of the jar is sealed. This is an instrument for detecting and measuring static electricity or voltage. Gold leaf electroscope.

It works on the principle that the like charges repel each other. Gold leaves are at the bottom of the rod. Electroscopes are placed in a glass case to diminish the effects of wind and ions in the air. Since electroscope is used to detect the presence of charge.

As you can see from the picture there is a metal conductor sphere and a metal rod attached to this sphere. The gold leaf electroscope was developed in 1787 by british clergyman and physicist abraham bennet as a more sensitive instrument than pith ball or straw blade electroscopes then in use. It is also determine the type of charge. It consists of a vertical metal rod which has two parallel strips of thin flexible gold leaf hang to it.

It consists of an evacuated glass jar placed on a nonconducting surface like wood. Two gold leaves are also attached at the bottom end of the rod. It consists of a vertical metal rod usually brass from the end of which hang two parallel strips of thin flexible gold leaf a disk or ball terminal is attached to the top of the rod where the charge to be. Invented by abraham bennet in 1787 this electroscope is comparatively more sensitive than a pith ball one.

Bennet s electroscope consisted of a pair of very thin narrow leaves of gold hung from a conducting rod. To prevent the gold leaf from drafts of air it is kept in a glass bottle. Gold leaf electroscope was developed by abraham bennet in the year 1787 which is more sensitive than pith ball electroscope. Metal rod has a metal knob at its top.

To prevent the gold leaf from drafts of air it is kept in a glass bottle. A metal disc is connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate.
