The metal leaf electroscope is a simple device used to detect the presence of electric charges. It consists of two thin metal leaves attached to a metal rod within a glass enclosure. When a charged object is brought close to the metal rod, the like charges repel the leaves, causing them to diverge and indicate the presence of an electric charge.
The metal case of a gold-leaf electroscope helps shield the delicate gold leaf from external influences such as drafts or static electricity. It also provides a stable and grounded environment for the electroscope to operate accurately.
There are two main types of electroscopes: gold-leaf electroscope and pith-ball electroscope. Gold-leaf electroscope uses thin gold leaves to detect electric charges, while pith-ball electroscope uses lightweight balls made of pith or other materials that can be attracted or repelled by electric charges.
To measure the charge of a charged body with a Gold Leaf Electroscope, you bring the charged body close to the electroscope's metal knob. The charge on the body induces a charge in the electroscope, causing the gold leaves to diverge. By observing the extent of divergence, one can estimate the magnitude of the charge on the body.
When a charged object is brought near the metal disc of a gold leaf electroscope, electrons move between the metal disc and the gold leaf, causing the gold leaf to become charged with the same type of charge as the object. This results in the gold leaf repelling from the metal disc, indicating that the object is charged.
An electroscope detects charge by using a metal rod or leaf that become charged when brought close to a charged object. The charged rod/leaf repels the like charges in the electroscope, causing them to move away from each other. This movement can be visually observed and indicates the presence of a charge.
To determine if a metal leaf electroscope is neutral, bring a charged rod near the metal cap. If the metal leaves diverge, the electroscope is neutral. If the metal leaves collapse or diverge more, the electroscope is positively charged.

An electroscope is typically used to test the charge of an object. It can detect the presence of a charge by the movement of a thin metal leaf or needle inside it. By bringing a charged object close to the electroscope, the leaf or needle will be repelled or attracted depending on the type of charge present.
The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope
A gold-leaf electroscope works by using charged objects to induce a charge on the metal leaves, causing them to repel each other and diverge. When a charged object is brought near the electroscope, it either transfers electrons to or takes electrons from the metal leaves, causing them to acquire a charge of the same polarity as the charging object. This charge separation results in the metal leaves repelling each other and diverging, indicating the presence of a charge.
An electroscope is the instrument used to detect static charge. It consists of a metal-leaf or needle that responds to the presence of electric charge by diverging from its equilibrium position.
The golden leaf electroscope can be charged positively by induction by first bringing a positively charged object close to the electroscope. The positive charges on the object attract the negative charges in the electroscope, causing the positive charges in the electroscope to be repelled to the leaves, thus giving the electroscope a positive charge.
