Chapter , Problem 30(choose chapter or problem)
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 21/6 (see the table in 4). Knowing this, and knowing that 1000 ft of 10-gauge copper wire has a resistance of approximately 1.00 0, estimate the resistance of 25 ft of 22-gauge copper wire
