Question

on what principle does the gold leaf electroscope work

Answer 1

hi there,

A gold-leaf electroscope is a simple device which is used to identify the electric charge present in a body.Their operation is based on the principle of like sign charge repulsion..

Answer 2

$\huge {\green {\sf {\underline {\underline{Answer}}}:-}}$

An electroscope is an instrument used for detecting electrical charge and its nature on a body. It was the first electrical charge detecting instrument. First electroscope was invented by the British physician William Gilbert. It is very sensitive and delicate instrument.

A gold-leaf electroscope consists of a brass rod which passes through a rubber stopper in a glass jar. The top end of the brass rod carries a brass disc and the lower end carries two thin good leaves such that they hang parallel to each other. The glass jar protects the gold leaves from the outside air currents. The lower part of the glass jar in the interior is surrounded by a metal foil.

When the electroscope is used, the metal foil is earthed. The increases the sensitivity of the electroscope. Some electroscopes have strips (leaves) of silver, copper, alluminium or brass instead of gold.
