일반물리학 2 — Current and Resistance: Problem 22

22 If the gauge number of a wire is increased by 6, the diameter is halved; if a gauge number is increased by 1, the diameter decreases by the factor \(2^{1/6}\) (see the table in Problem 44). Knowing this, and knowing that 1000 ft of 10-gauge copper wire has a resistance of approximately 1.00 \(\Omega\), estimate the resistance of 13 ft of 22-gauge copper wire.
