Apparatus for Distributing Electric Charges
Product Code : SCL-PL-11835
Apparatus for Distributing Electric Charges (SKU SCL-PL-11835) is an electrostatics set for showing how charge produced by friction spreads over and between conductors, with a 200 mm gold leaf electroscope to detect it. Physics teachers use it for Class 9–12 electrostatics and introductory college demonstrations. The set comes from Science Lab Supplies' own factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, where it is manufactured, and is sold without middlemen to schools, colleges, tender contractors and distributors.
Specifications
The set centres on a gold leaf electroscope of 200 mm diameter and four metal spheres on a 50 mm plastic insulating handle. Friction materials (nylon, celluloid and polyethylene tapes and a cloth), two aluminium cans and small conductors let students charge, transfer and compare charge on different bodies.

Applications and Experiments for the Electric Charge Distribution Apparatus
Pupils charge insulating materials by rubbing, transfer charge to the spheres and cans on insulated handles, and read the result on the gold leaf electroscope. Comparing readings taken from different parts of a charged conductor shows that charge sits on outer surfaces and gathers where the surface curves most sharply.
- Class 9–10 science: charging by friction, conduction and induction.
- Class 12 physics: electric charges and fields, charge on the surface of a conductor.
- Teacher training and college demonstrations of the gold leaf electroscope.
Electrostatic work is most reliable in dry air; keep the handles and leaves clean and dry before each lesson.
Standard Scope of Supply
Each set contains the four metal spheres on their insulating handle, a second insulating handle, the electroscope-plate handle with polyethylene tape sheet, nylon wraps, two aluminium cans, celluloid tape, a wire stirrer, a friction cloth, a chrome wire hook, the 200 mm gold leaf electroscope and a demonstration table for the charge-distribution apparatus.

Frequently Asked Questions
What does the Apparatus for Distributing Electric Charges demonstrate?
It shows how charge made by rubbing moves to conductors and spreads over their surfaces, using metal spheres, aluminium cans and a 200 mm gold leaf electroscope to detect it.
Is an electroscope included?
Yes. A gold leaf electroscope with a diameter of 200 mm is part of the set, together with the friction materials and insulating handles.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures this apparatus. Its factory is in Saha, Ambala, India, and because the quotation is prepared there, buyers get prices and details at source.
Why do readings vary from day to day?
Humidity lets charge leak away. Dry the handles, cloth and electroscope before use and repeat readings quickly for consistent results.
