Wire thickness is typcially measured with the term Gauge (AWG). The smaller the gauge, the thicker the wire. One of the most common gauge wire used in household wiring is 12 gauge wire which has a diameter of 2.05 mm. The wiring that comes into a house (rated for 200 amps) is typcially 0 gauge wire which has a diameter of 8.25 mm. The resistivity of the wire is 2x10⁻⁸ Ωm.
If the wire from the power pole to the house is 16 m long, what is it's resistance? (The power may be underground in some towns) and If 170 A of current is being used, how much power is dissipated in that wire?
