A Gold Leaf Electroscope

The gold leaf electroscope.

A gold leaf electroscope.

It consists of a vertical metal rod which has two parallel strips of thin flexible gold leaf hang to it. It consists of a vertical conductive rod with a metal ball on the top and two thin and parallel strips of gold leaf attached at the bottom. Metal rod has a metal knob at its top. It consists of an evacuated glass jar placed on a nonconducting surface like wood.

Gold leaves are at the bottom of the rod. To prevent the gold leaf from drafts of air it is kept in a glass bottle. Electroscopes are placed in a glass case to diminish the effects of wind and ions in the air. Electroscope it is a device that is used for detecting whether an object is charged or uncharged.

Bennet s electroscope consisted of a pair of very thin narrow leaves of gold hung from a conducting rod. 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. It consists of a metal rod which is fitted in an insulating box.

It works on the principle that the like charges repel each other. Gold leaf electroscope was developed by abraham bennet in the year 1787 which is more sensitive than pith ball electroscope. The mouth of the jar is sealed. Two gold leaves are also attached at the bottom end of the rod.

The whole of this part of the electroscope is insulated from the body of the instrument. This is an instrument for detecting and measuring static electricity or voltage. It is also determine the type of charge. The gold leaf electroscope like the one illustrated here first appeared in the latter part of the 18th century.

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. To prevent the gold leaf from drafts of air it is kept in a glass bottle. Gold leaf electroscope. As you can see from the picture there is a metal conductor sphere and a metal rod attached to this sphere.

Since electroscope is used to detect the presence of charge. Invented by abraham bennet in 1787 this electroscope is comparatively more sensitive than a pith ball one.
