Failure Current of DexMat CNT Yarn

In this video we demonstrate the amount of electric current that our 500 micron diameter CNT yarn can sustain in air, and compare this to a copper wire measured with the same apparatus and environment. Here are the precise properties of the materials used in these tests:

The CNT yarn has an average diameter of 500 microns, a linear mass of 0.18 mg/m, and a linear resistance of 1.3 Ohms/m.

The copper wire is a 36 gauge wire with a diameter of 127 microns, a linear mass of 0.26 mg/m, and a linear resistance of 0.59 Ohms/m.

Note that the voltage measurements shown on the power supply display represent the voltage drop through the entire circuit, not only across the sample being measured.
