A Gold Leaf Electroscope Can Be Used

In this electroscope two thin leaves and an electrically conductive material are hung adjacent and virtually in contact with each other.

A gold leaf electroscope can be used.

Two gold leaves are also attached at the bottom end of the rod. A leaf electroscope requires a minimum weight in the leaves so that the very weak force exerted by practical voltages will cause significant separation. It works on the principle that the like charges repel each other. It consists of a metal rod which is fitted in an insulating box.

It consists of an evacuated glass jar placed on a nonconducting surface like wood. Metal rod has a metal knob at its top. Since electroscope is used to detect the presence of charge. 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.

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. 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. 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.

Answer is d the gold leaf electroscope has been used by physicists for hundreds of years. It consists of a vertical metal rod which has two parallel strips of thin flexible gold leaf hang to it. This is an instrument for detecting and measuring static electricity or voltage. Gold leaf electroscope was developed by abraham bennet in the year 1787 which is more sensitive than pith ball electroscope.

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. The gold leaf electroscope like the one illustrated here first appeared in the latter part of the 18th century. It is a simple device to detect the presence of charge on any body. Abraham bennet a clergyman and man of science first described the instrument in philosophical transactions in 1787.

Its operation is based on the principle of electrostatic induction and like charge repulsion. Gold leaf electroscope. The gold leaf electroscope. This instrument is used for the detection of charge and measuring static electricity.

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