Gold Leaf Electroscope
A Gold Leaf Electroscope is an instrument which detects the electrical charge present in an object.
Electroscope is very simple to construct. It has 3 main parts
- A thin gold sheet bend at an angle
- An aluminium rod and a container
- A top metallic ball for receiving charge
Working and concept:
Like charges repel each other and opposite charges attract. This is the working principle behind the GLE. When a gold leaf suspended in an electroscope experiences charge on its two opposite leaves, it creates a force of separation. If a charge is induced it will repel the leaves away from each other. Greater the magnitude of charge, the greater will be separation between the leaves.
