Gold leaf electroscope it is a simple device to detect the presence of charge on any body.Construction it consists of a metal rod which is fitted in an insulating box.Metal rod has a metal knob at its top.Two gold leaves are also attached at the bottom end of the rod.Working since electroscope is used to detect the presence of charge.
Charge can be transferred to the electroscope by wiping a charged rod or balloon on the top plate.The electroscope is actually measuring the potential difference between the earth and the plate.Because of the cost of real gold leaf, schools tend to use dutch metal, an alloy of 80 copper and 20 zinc.
Induction and the gold-leaf electroscope it is always observed that the leaves of an electroscope diverge when a charged body is brought near its cap, without touching it.This we can now easily understand if, for example, we bring a negatively charged rod near the cap, it induces a positive charge on the cap, and a negative one on the leaves.Read More
The gold leaf electroscope, like the one illustrated here, first appeared in the latter part of the 18th century.Abraham bennet, a clergyman and man of science, first described the instrument in philosophical transactions in 1787.Bennets electroscope consisted of a pair of very thin, narrow leaves of gold hung from a conducting rod.Read More

The leaf rises because it is repelled by the stem support.The leaf and its support have the same type of charge.A typical school electroscope will show a deflection for a charge as small as 0.01 pc the unit pc is a pico coulomb, 1 10-12 coulombs, equivalent to the charge on over 6 million electrons.Charging an electroscope.Read More
This sturdy electroscope features a metal case with front and rear glass windows for preventing air currents from affecting the deflection of the leaves.Leaves are gold and aluminum.Leaf support rod is held in place by an insulating plastic sleeve.A graduated scale is also provided for measuring the deflection from 0 to 90 degrees.Read More
Eisco labs gold leaf electroscope this gold leaf electroscope is great for hands on experience with electrostatic principles in physics classrooms and labs.The solidly constructed sheet anodized aluminum walls of the electroscope are mounted on a plastic base.Front glass window slides up to allow insertion of ionizing material in chamber.Read More
Gold leaf electroscope it is an instrument for detecting and measuring static electricity or voltage.A metal disc is connected to a narrow metal plate and a thin piece of gold leaf is fixed to the plate.Read More
A glass rod rubbed with silk is used to charge a gold leaf electroscope and the leaves are observed to diverge.The electroscope thus charged is exposed to x-rays for a short period.Then a.The divergence of leaves will not be affected.B.Read More

Function of each part of gold leaf electroscope 1.The whole of this part of the electroscope is insulated from the body of the instrument.When a charge is put on the disc at the top it spreads down to the plate and leaf.This means that both the leaf and plate will have the same charge.Similar charges repel each other and so the leaf.Read More
For example, if we rub the both hands together and place it on the above gold leaf electroscope, the gold leaves will be repelled, but as soon we remove our hands from the plate of the gold leaf electroscope, the leaves will come to normal position.Read More
