Discussion Overview

The discussion revolves around the American Wire Gauge (AWG) system, specifically its relationship to resistivity and circular mils. Participants explore the properties of different wire gauges and their resistive values, as well as reference external resources for further information.

Discussion Character

  • Technical explanation, Conceptual clarification

Main Points Raised

  • One participant asks about the relationship between American Wire Gauge, resistivity, and circular mils.
  • Another participant suggests that the information can be found through a search engine, indicating that it is readily available online.
  • A third participant reiterates the initial question and provides a link to a Wikipedia entry on American Wire Gauge, suggesting it as a useful resource.
  • A participant provides specific resistive values for various wire gauges, noting that 0 gauge has about 0.1 ohms per 1000 feet, while 40 gauge has about 1000 ohms per 1000 feet.

Areas of Agreement / Disagreement

There is no clear consensus on the initial question regarding the relationship between AWG, resistivity, and circular mils, as participants provide varying levels of engagement and information without resolving the inquiry.

Contextual Notes

The discussion lacks detailed explanations of the underlying principles of resistivity and circular mils, and the resistive values provided are specific to copper wire without broader context.

what is american wire gauge with relation to resistivity and circular mils??
 
Engineering news on Phys.org
Google it. I have many times. It's there, you just need to look.

Wikipedia has a nice entry:

http://en.wikipedia.org/wiki/American_wire_gauge

I think I'll add that to the EE resources stickie thread at the top of the EE forum...
 
Note that for copper wire
0 gauge is about 0.1 ohms per 1000 feet
10 gauge is about 1.0 ohms per 1000 feet
20 gauge is about 10 ohms per 1000 feet
30 gauge is about 100 ohms per 1000 feet
40 gauge is about 1000 ohms per 1000 feet
