Electrical Nichrome Wire 100gm

Product Description

STEMAids Electrical Nichrome Wire 100gm provides nichrome wire in a stated net quantity of 100 g. Nichrome refers to nickel–chromium resistance alloys that typically provide higher electrical resistance than an equivalent copper conductor. The exact nickel–chromium composition and alloy grade of this product must be confirmed.

The wire supports practical study of Ohm’s law, resistivity, resistance per unit length and Joule heating. Students can compare measured sections or observe how current produces heat in a resistance wire. Safe use depends on the confirmed diameter, resistance, temperature rating and maximum permissible current.

Key Features

• Defined 100 g quantity: Provides a manageable amount for classroom experiments and laboratory preparation.
• Nichrome resistance alloy: Supports compatible experiments requiring electrically resistive wire.
• Visible heating effect: Demonstrates the conversion of electrical energy into heat under controlled conditions.
• Useful for resistivity studies: Helps students examine how wire length and diameter affect resistance.
• Easy material allocation: Laboratory staff can issue measured sections to different practical groups.
• Suitable for low-voltage circuits: Can be used with an approved, current-limited laboratory supply.
• Reusable offcuts: Clean sections that have not been overheated or damaged may be retained.

How to Use the Electrical Nichrome Wire 100gm

1. Confirm the wire gauge, resistance per metre and safe current limit.
2. Measure and cut the required length with suitable wire cutters.
3. Mount the wire securely on a heat-resistant experiment board or support.
4. Keep the wire clear of skin, paper, plastic and combustible materials.
5. Connect it to a current-limited, low-voltage laboratory power supply.
6. Increase current only within the approved experimental procedure.
7. Disconnect the supply before adjusting or replacing the wire.
8. Allow the wire to cool completely before touching or storing it.

Safety note: Nichrome wire can become extremely hot while energised. Never touch live or recently heated wire, operate it near combustible materials, or connect it directly to mains electricity.

Care & Maintenance

• Store unused wire on its spool or in a dry, clearly labelled container.
• Avoid sharp bends, knots and repeated flexing at the same point.
• Discard sections that are heavily oxidised, brittle, kinked or overheated.
• Keep different gauges separately labelled because diameter affects resistance and heating behaviour.

Frequently Asked Questions

What is Electrical Nichrome Wire 100gm used for?

It is used for resistance, resistivity and controlled electrical-heating experiments in supervised physics laboratories.

What is nichrome wire made of?

Nichrome is a nickel–chromium resistance alloy family. The exact alloy composition of this STEMAids wire must be confirmed from its technical specification.

Why does nichrome wire become hot?

Nichrome resists the flow of current and converts electrical energy into heat. The temperature reached depends on wire resistance, current, dimensions and heat dissipation.

How long is 100 g of nichrome wire?

The total length depends on the wire diameter and alloy density. It cannot be stated accurately until the gauge and alloy grade are confirmed.

Is the nichrome wire insulated?

No insulation or covering is confirmed. Treat the wire as an exposed conductor unless the approved specification states otherwise.

Can nichrome wire be connected directly to mains electricity?

No. It should be used only with an approved, current-limited, low-voltage laboratory supply under trained supervision.
