Point-shaped conductor Manufacturer,Supplier and Exporter in India
Product Code : SCL-ES-12908
The Educational Instrument Point-shaped conductor is an electrostatics demonstration accessory that helps students observe how electric charge collects more intensely at sharp points than on broad or rounded surfaces. This makes it useful for explaining point discharge, charge leakage, ionization of air, and the behaviour of conductors in strong electric fields.
This apparatus is generally used with a compatible electrostatic generator, Van de Graaff generator, or static electricity machine. It helps convert abstract electrostatic theory into observable classroom demonstrations. For related teaching apparatus, view our Electrostatics & Sound equipment and Physics Lab Equipment.

How to Use the Point-shaped conductor
Place the compatible electrostatic generator on a clean, dry, stable laboratory bench.
Mount the Point-shaped conductor securely on the recommended terminal or support.
Check that the pointed end is clean, dry, and correctly positioned for the demonstration.
Operate the electrostatic machine gradually under teacher supervision.
Observe point discharge effects, charge leakage, or nearby movement of lightweight indicators.
Compare the behaviour with a rounded conductor if the lesson requires comparison.
Stop the electrostatic machine and discharge all connected parts before handling.
Safety note: Use only under trained supervision. Keep hands dry, avoid touching charged conductors, and discharge the apparatus before adjustment, removal, or storage.
Care & Maintenance
Store the Point-shaped conductor in a dry cabinet to reduce moisture-related charge leakage.
Keep the pointed conducting surface clean and free from dust, oil, or corrosion.
Inspect the mounting and connection point before every demonstration.
Do not use the apparatus if the point, support, or connector is loose, bent, or damaged.

The Point-shaped conductor supports clear classroom demonstrations of electrostatic field concentration and helps teachers explain why sharp conductors discharge more readily than rounded surfaces.
Frequently Asked Questions
What is a point-shaped conductor apparatus used for?
A point-shaped conductor apparatus is used to demonstrate charge concentration, point discharge, corona effect, and electric field behaviour near sharp conducting surfaces.
Why does charge concentrate at a pointed conductor?
Charge density becomes higher at sharp points because the local curvature is greater. This creates a stronger electric field near the point and can lead to easier discharge into the surrounding air.
Can the Point-shaped conductor be used with a Van de Graaff generator?
Yes, it can be used with a compatible Van de Graaff generator or other suitable electrostatic machine. Final mechanical and electrical compatibility should be confirmed before purchase.
Is this apparatus suitable for school physics laboratories?
Yes. The Point-shaped conductor is suitable for school and college physics laboratories when used under teacher supervision and with proper electrostatic safety handling.
Does the Point-shaped conductor have a capacity?
No. The Point-shaped conductor is a non-volumetric electrostatics apparatus, so liquid capacity or measuring capacity is not applicable.
What should be checked before using the conductor?
Check that the conductor is dry, the point is clean, the support is stable, and the electrostatic machine can be discharged safely after the demonstration.
