#2 AWG (American Draht Gauge) Eigenschaften: Durchmesser, Fläche, Widerstand.
Der Durchmesser des #2 AWG Drahts in Zoll:
d2(Zoll) = 0.005 Zoll × 92 (36-2)/39 = 0.2576 Zoll
d2(mm) = 0.127 mm × 92 (36-2)/39 = 6.5437 mm
Die Fläche des #2 AWG Drahts in Kilo-Circular-Mils:
An (kcmil) = 1000×dn2 = 1000×(0.2576 Zoll)2 = 66.3713 kcmil
Die Fläche des #2 AWG Drahts in Quadratzoll:
A2(Zoll2) = (π/4)×dn2 = (π/4)×(0.2576 Zoll)2 = 0.0521 Zoll2
A2(mm2) = (π/4)×dn2 = (π/4)×(6.5437 mm)2 = 33.6308 mm2

* Results may change with real wires: different resistivity of Material and number of strands in wire
The n gauge wire resistance R in ohms pro Kilofuß (Ω/kft) is equal to 0.3048×1000000000 times the wire's resistivity ρ in Ohm-Metern (Ω·m) geteilt durch 25.42 mal der Querschnittsfläche An in Quadratzoll (in2):
Rn (Ω/kft) = 0.3048 × 109 × ρ(Ω·m) / (25.42 × An (in2))
The n gauge wire resistance R in ohms pro Kilometer (Ω/km) is equal to 1000000000 times the wire's resistivity ρ in Ohm-Metern (Ω·m) geteilt durch die Querschnittsfläche An in Quadratmillimeter (mm2):
Rn (Ω/km) = 109 × ρ(Ω·m) / An (mm2)
