Click here to return to nichrome wire sales page. Use this calculator to find the right nichrome wire size, length and power supply for your application. There are four variables involved in determining what you need: voltage, gage, length, and temperature. Each affects the others. Set three, calculate the fourth.

It generally refers to alloys in wire and ribbon form.

Nichrome is also known as Nickel-chromium (NiCr). In electric ignition systems, it is mainly used as a bridge wire in the explosives (bombs) and fireworks industries. Reduce current by half for coiled wire. And carefully check resistance when the wire is at the temperature you want (after you disconnect the power). Measure its resistance at a known temperature, and calculate what resistance you expect at the desired temperature.

This article describes how . At the bottom of the page you can learn how to manually calculate your requirements, but this online calculator is SO fantastic it is all you need! The resistance through the wire is ~0.

R, and increase in R due to heating up . So according to the formula L is 8. To verify the surface loading, W is 7. If your calculated surface loading is . Pick the material which you will use to be the hot wire. The operating voltage of the stove is 2volts AC ( alternating current). With this information, you can calculate wire . Please choose either: Round Wire.

Enter dimensions: Wire Diameter: 0. Tape Width: Tape Thickness: Reset. Ohms per metre: Ohms per yard: Ohms per foot: 0. Metres per kg: Feet per lb: Tolerance Range. This Pin was discovered by Ida Johansson.

Cirris Systems provides you with a calculator to measure wire resistance. The most common usage is as resistance wire , although they are also used in some dental restorations (fillings) and in a few .

Info: NiChrome wire test: 32Awg, 0. If a potential difference of 10. V is maintained across a 1. The wire is melted down and recast with twice its original length. Find the new resistance . Experiment to calculate the diameter of a piece of nichrome wire from its electrical resistance by varying the length of the wire.

Extracts from this document. IB Group Internal Assessment ChemistryBiologyPhysics. Describe the procedure used in measuring the length of the sample of wire.

Use the data to calculate the resistivity of nichrome.
