Question 535071: The resistance of a wire is inversely proportional to the square of its diameter. If an AWG (American wire gauge) size 12 conductor (0.0808-in. diameter) has a resistance of 14.8, what will be the resistance of an AWG size 10 conductor (0.1019-in. diameter) of the same length and material?

14.8*0.0808^2 = R*0.1019^2
R = 14.8*0.0808^2/0.1019^2
R =~ 9.3 ohms
