Electrical Nichrome Wire 100gm

Quick answer: This 100gm spool of Nichrome resistance wire is used in physics laboratories to build resistance coils, heating elements and circuit-experiment components, thanks to nichrome’s high electrical resistivity and resistance to oxidation at high temperatures.

Description

Nichrome is an alloy of nickel and chromium prized in laboratory and educational use for its high, stable electrical resistance and its ability to withstand heating without rapidly oxidising or burning out — which is why it is the standard choice for winding resistance coils and simple heating elements used in Joule’s Law and calorimetry experiments.

Supplied as a 100gm spool, this wire lets teachers and lab technicians wind custom-length resistance coils to a required resistance value for a given experiment, rather than relying only on pre-made fixed resistors.

Specifications

Safety Note

Nichrome wire can become very hot when carrying current – never touch a wound coil while current is flowing, and allow it to cool before handling. Use only with appropriately rated low-voltage classroom power supplies and switch off before making circuit changes.

Frequently Asked Questions

Why is nichrome used for resistance wire instead of plain copper?

Nichrome has much higher electrical resistivity than copper and resists oxidation even when heated, making it well suited to winding resistance coils and heating elements that must carry current repeatedly without burning out.

How much wire do I get with this listing?

This listing supplies a 100 gram spool of nichrome wire. The exact gauge/diameter is not specified for this listing; contact our sales team to confirm before ordering.

Can I use this wire to make a custom-resistance coil?

Yes, winding a known length of nichrome wire to a target resistance is a common school and college lab activity, often paired with a multimeter to verify the resulting resistance value.

Is nichrome wire safe to touch while a circuit is on?

No. It can become hot while carrying current. Always switch off the supply before handling a wound coil, and allow it to cool first.

What experiments commonly use nichrome wire?

It is common in Joule’s Law of heating experiments, calorimetry practicals, and any activity where students build a custom resistance element from raw wire.

How should I store the wire spool?

Keep it wound neatly on its spool in a dry location to prevent kinking, tangling or corrosion of the wire surface.
