A Gold Leaf Electroscope Can Be Used

The mouth of the jar is sealed.

A gold leaf electroscope can be used.

To prevent the gold leaf from drafts of air it is kept in a glass bottle. Gold leaf electroscope. This is an instrument for detecting and measuring static electricity or voltage. A leaf electroscope requires a minimum weight in the leaves so that the very weak force exerted by practical voltages will cause significant separation.

The gold leaf electroscope. It consists of an evacuated glass jar placed on a nonconducting surface like wood. Answer is d the gold leaf electroscope has been used by physicists for hundreds of years. This instrument is used for the detection of charge and measuring static electricity.

Abraham bennet a clergyman and man of science first described the instrument in philosophical transactions in 1787. Gold leaf electroscope was developed by abraham bennet in the year 1787 which is more sensitive than pith ball electroscope. It works on the principle that the like charges repel each other. Two gold leaves are also attached at the bottom end of the rod.

Since electroscope is used to detect the presence of charge. Inventor of the gold leaf electroscope englishmen sir abraham bennet 1786 anno domini principle of a gold leaf electroscope a gold leaf electroscope is a simple device which is used to identify. It indicates the presence and nature of a charge through the application of charge to a metal top plate connected through a stem to two pieces of gold leaf. It consists of a vertical metal rod which has two parallel strips of thin flexible gold leaf hang to it.

Because gold is unequaled when it comes to ductility. The whole of this part of the electroscope is insulated from the body of the instrument. 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. A gold leaf electroscope is used for detecting electric charge present in a body and identifying its polarity.

Metal rod has a metal knob at its top. The gold leaf electroscope like the one illustrated here first appeared in the latter part of the 18th century. Its operation is based on the principle of electrostatic induction and like charge repulsion. A metal disc is connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate.

The movement of one piece of gold leaf away from the other shows that the electroscope is charged hence a gold leaf electroscope can detect the. It consists of a metal rod which is fitted in an insulating box. It is a simple device to detect the presence of charge on any body. While gold is one of the densest metals.
