Can this above rubbish go please?--DaveDodgy (talk) 15:57, 10 May 2008 (UTC)
Highest resistivity?
editWhat's the highest resistivity resistance wire available? I know you can get wirewound resistors used for high voltage 'ballast' resistors in gas LASERs that are in the 100's of KΩ. So what are they made of? Or are they just normal resistance wire but ULTRA thin ?
When making a heating element, would a higher resistivity resistance wire be more efficient? And therefore drain a battery LESS, to provide the same amount of heat? --DaveDodgy (talk) 15:57, 10 May 2008 (UTC)
The Table
editIt should be removed. There is no source provided. Plus it is misleading since resistance will vary drastically with wire thickness (important data that is not included on the table). —Preceding unsigned comment added by 99.242.1.235 (talk) 23:41, 17 March 2009 (UTC)
- Done (commented out). A working one with real units could be substituted or built on this. 91.154.87.201 (talk) 11:24, 10 January 2013 (UTC)
Carbon (amorphous) resistivity
editContradictory data for amorphous carbon resistivity. Text says: "The resistivity of amorphous carbon actually has a range of 3.8 - 4.1 × 10−6 Ω m." From the table, "Carbon (amorphous) 3.95 10−6 Ω-cm". Note the units: Ohm*m in one case, Ohm*cm in another. Both values seems to be wrong. Actual resistivity (see here for example) is about 35×10−6 Ω*m --Shcha (talk) 14:20, 6 January 2017 (UTC)
