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. It suits Class 9–12 electrostatics and introductory college demonstrations. Science Lab Supplies manufactures the set in its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and schools, colleges, tender contractors and distributors receive their quotation from there with no middleman.
Specifications
The charge-distribution set's conductors, handles and friction materials are listed separately in the table. In short, a 200 mm gold leaf electroscope works with four metal spheres on a 50 mm insulating handle, two aluminium cans and small conductors, while nylon, celluloid and polyethylene materials and a cloth produce charge by rubbing.

Applications and Experiments for the Electric Charge Distribution Apparatus
Pupils can 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 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, then stored charge on the Parallel-Plate Capacitor.
- 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.
Packing, MOQ and Lead Time
You may ask for one set or several for group work. Each quotation confirms packing, delivery time and price for the requested quantity, and any other electrostatics items from the school physics lab equipment range can be priced on the same document.
Registered with an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. An electrostatics price list for your school can be requested on the contact page or built up in the enquiry cart, and the lab tender page covers tendered supply.
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, the insulating handles, the aluminium cans and the demonstration table.
Is Science Lab Supplies the manufacturer or a trader?
The charge-distribution set is manufactured at the Science Lab Supplies factory in Saha, Ambala, India, and because the quotation is prepared there too, 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; a Digital Thermo-Hygrometer can show the room humidity before a lesson.
