Gold Leaf Electroscope Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12406
Jlab Export is a leading Gold Leaf Electroscope Manufacturer,and suppliers in India
Gold Leaf Electroscope (code EL-PL-12406) is a charge detector in which a gold leaf hangs from a plated blade below an insulated disc electrode, inside a sheet metal case with sliding glass panels and a clear 0–90° scale. Physics classes use it to study charging by contact and by induction and to compare charges by the leaf’s deflection. The electroscope is built by JLab in Ambala, India.

How the Leaf Shows Charge
When a charged body touches the disc, the charge spreads over the disc, the blade and the leaf. Leaf and blade then carry like charges and repel, so the leaf swings out; the angle it reaches on the acrylic scale lets two charges be compared, a wider angle meaning more charge. The moulded plastic bush separates the electrode from the metal body, which stops the charge draining to the case, and the terminal on the side lets the case itself be earthed.
Induction, Testing a Charge and Ionisation
To charge by induction, hold a charged rod near the disc, touch the disc briefly with a finger to earth it, then take the finger away before the rod; the leaf falls when the disc is earthed and opens again once the rod is removed, now with a charge opposite to that of the rod. To test an unknown charge, bring it towards the disc of an electroscope that is already charged: if the leaf opens further, the two charges are alike. The clear front slides up so that leaves can be fitted and an ionising source placed in the chamber; ionised air lets the charge leak away and the leaf falls slowly. The ground glass back gives an even background against which the thin leaf is easy to watch.
Other Electrostatics Apparatus
- Electroscope with Aluminum Arrow — similar sheet metal case with an aluminium arrow in place of a leaf.
- Pith Ball Electroscope — two pith balls on silk thread for showing attraction and repulsion.
- Glass Rod with Rubbing Material — glass rod and cloth for charging the disc by friction.
Magnetism, current electricity and further electrostatics items sit in the Physics Lab range.
