Constantan Wire (100gm) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11251
Constantan is a resistance-alloy material commonly used where comparatively stable electrical resistance is required. In educational experiments, a measured length of constantan wire can form the test conductor in circuits used to investigate resistance, resistivity and the relationship between conductor dimensions and electrical behaviour.
The product is supplied in a nominal 100 gm quantity. Wire gauge, diameter, total length, exact alloy composition, resistance per metre, insulation, finish and temperature rating are not specified. Buyers should confirm these parameters before selecting the wire for a prescribed practical, replacement requirement or procurement specification.

How to Use the Constantan Wire (100gm)
Confirm the wire gauge required by the experiment.
Inspect the wire for kinks, corrosion or surface damage.
Measure and cut the required length with a suitable wire cutter.
Secure the wire between compatible terminals without overstretching it.
Connect an ammeter in series and a voltmeter across the test length.
Use a current-limited, low-voltage laboratory power supply.
Apply current briefly and record the voltage and current readings.
Disconnect the supply before changing the wire length or connections.
Safety note: Never connect the wire directly to mains electricity. Excessive current can heat the wire and cause burns. Use a current-limited supply under trained supervision.
Care & Maintenance
Store unused wire in a dry, clearly labelled container.
Avoid sharp bends, crushing and unnecessary stretching.
Disconnect experimental sections immediately after use.
Replace wire showing corrosion, overheating or permanent deformation.

Frequently Asked Questions
What is Constantan Wire (100gm) used for?
It is used for compatible resistance, resistivity, Ohm’s law and electrical circuit experiments. The precise application depends on the wire gauge and resistance value.
How much constantan wire is supplied?
The product is supplied as a nominal 100 gm quantity. The resulting wire length depends on its diameter and density.
What is the wire diameter?
The diameter or wire gauge is not specified. Buyers should state the required SWG, AWG or metric diameter when requesting a quotation.
Is the constantan wire insulated?
The presence and type of insulation are not confirmed. Treat the wire as uninsulated unless the current specification states otherwise.
Can it be used for an Ohm’s law experiment?
Yes, provided its gauge, length and resistance suit the low-voltage circuit and measuring instruments being used.
Can constantan wire become hot?
Yes. Any resistance wire can heat when excessive current passes through it. Current must remain within the safe experimental limit.
