8 gauge copper wire has a diameter of 3.26 mm, while 12 gauge copper wire has a diameter of 2.05 mm. For the following lengths of wire, which must have the lowest resistance?
40 cm of 8 gauge wire
40 cm of 12 gauge wire
80 cm of 12 gauge wire
80 cm of 8 gauge wire
(work the problem out with explanation)
Homework Answers
Resistance of a wire is given by R= resistivity*length/area
Therefore, least resistance will be observed in the wire with least value of length/area
This means the wire with low length and high diameter will have least resiatance.
Among the given options, the wire that satisfies this criteria is 40 cm of 8 gauge wire
This is the required answer

Residential building codes typically require the use of 12-gauge copper wire (diameter 0.205 cm) for wiring receptacles. Such circuits carry currents as large as 20.0 A. If a wire of smaller diameter (with a higher gauge number) carried that much current, the wire could rise to a high temperature and cause a fire. (a) Calculate the rate at which internal energy is produced in 1.15 m of 12-gauge copper wire carrying a current of 20.0 A. (b) Repeat the calculation...
