Why is only a gold leaf used in gold leaf electroscope?
Gold is a very good material for leaf-type electroscope. It is very soft and light and conductive, while being non-corrosive. Other materials can be used but none seem quite as good.
Why in gold leaf electroscope sides parallel to the gold leaf are tin foils?
They are used to store charges, like a capacitor.
Principle of electroscope and types of electroscope?
Like charges repel and unlike charges attract each other this is the fundamental principle used in an electroscope to detect presence and amount of charge. There are mainly 2 tpes of electroscopes pith ball electroscope and gold leaf electroscope
What is gold leaf electroscope?
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 the electric charge present in a body.CONSTRUCTION OF A GOLD-LEAF ELECTROSCOPE:-1) A gold-leaf electroscope is a metallic disk attached to one end of a copper rod.2) To the other end of the copper rod, two thin gold metal leaves are attached. (Usually of gold. Can also be of another metal.)3) The side of the copper rod with the thin gold leaves is fitted inside a conical flask, through a non-conducting rubber-cork.4) The thin gold leaves are used in a electroscope to make it more sensitive.WORKING OF A GOLD-LEAF ELECTROSCOPE:-1) If an uncharged body is brought and touched on the metallic disk, we notice no change in the golden leaves.2) If a charged body (positively or negatively charged) is brought and touched to the metallic disk of the gold-leaf electroscope, it attains the same charge as that of the charged body touched to the metallic disk by the property of transmission of charges from one charged substance to another substance.3) Therefore, the golden leaves in the electroscope also attain like charges and diverge from each other due to the repulsion.4) The repulsion of the golden leaves in the electroscope is the test for finding out that whether a body is charged or not.5) If we touch any of the charged bodies, the charge escapes from our body directly to the earth through our legs.6) The charged body thus loses it's charge and becomes neutral.
Uses of an electroscope?
An electroscope can be used to determine the charge of an object.

What type of instrument can detect the presence of an electrical charge?
a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge.
Uses of an electroscope?
An electroscope can be used to determine the charge of an object.
Is gold used in windows?
Stained-glass windows, yeah; gold is used to make glass red.
What food has gold leaf in it?
The liqueur known as "Goldwasser" has a small quantity of gold leaf suspended in it. Gold leaf could also be used for decoration on cakes or pastries.
How can gold leaf electroscope be used to detect an electric charge?
In order to identify the charge of a body we should use a charged electroscope. Let us say the electroscope is negatively charged. Now bring the unknown charged body 'X' near the cap of the electroscope. If the leaves diverge more the charge in 'X' must be negative. Suppose that the leaves close a little when 'X' is brought near 'C', then 'X' may have a positive charge or it may not have any charge. In order to confirm the positive charge you must bring the rod 'X' near the cap of a positively charged electroscope. If the leaves diverge more, then 'X' has positive charge.
What is the instrument that is used to detect static charge?
An electroscope is an instrument used to detect static electricity.
What is gold leaf used for?
Well, one thing it is used for is decorating, i guess. It would be insanely expensive if you used actuall gold and put it on, for example, a clothing chest, so they just use a thin layer of gold leaf.
