2. American wire gauge - Wikipedia

   en.wikipedia.org/wiki/American_wire_gauge

   (E.g. 1 mm diameter wire is ~18 AWG, 2 mm diameter wire is ~12 AWG, and 4 mm diameter wire is ~6 AWG). This quadruples the cross-sectional area and conductance. A decrease of ten gauge numbers (E.g. from 12 AWG to 2 AWG) multiplies the area and weight by approximately 10, and reduces the electrical resistance (and increases the conductance ) by ...

3. IEC 60228 - Wikipedia

   en.wikipedia.org/wiki/IEC_60228

   Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...

4. Electrical resistivity and conductivity - Wikipedia

   en.wikipedia.org/wiki/Electrical_resistivity_and...

   Original data from the 1911 experiment by Heike Kamerlingh Onnes showing the resistance of a mercury wire as a function of temperature. The abrupt drop in resistance is the superconducting transition. The electrical resistivity of a metallic conductor decreases gradually as temperature is lowered.

5. Wire gauge - Wikipedia

   en.wikipedia.org/wiki/Wire_gauge

   A device for measuring American wire gauge. Wire gauge is a measurement of wire diameter. This determines the amount of electric current the wire can safely carry, as well as its electrical resistance and weight.

6. Electrical resistivities of the elements (data page) - Wikipedia

   As quoted in an online version of: David R. Lide (ed), CRC Handbook of Chemistry and Physics, 84th Edition.CRC Press. Boca Raton, Florida, 2003; Section 4, Properties of the Elements and Inorganic Compounds; Physical Properties of the Rare Earth Metals

7. Electrical resistance and conductance - Wikipedia

   en.wikipedia.org/wiki/Electrical_resistance_and...

   Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...
