{"Image DocumentName": "Practice Determine the resistance of a 1-mile length of 12-gauge copper wire. (Hint:1 mile = 1609 m; diameter of 12 gauge copper wire = cm)", "Image ImageDescription": "L = 1609 m, A = \u03c0R2. \u03c1= 1.7 x 10-8 \u03a9\uf0d7m. First, find the cross-sectional area: A = \u03c0\u2022r2 = (3.14) \u2022 [ ( m) / 2)]2 = x 10-6 m2. Now, substitute into the above equation to determine the resistance. R = (1.7 x 10-8 \u03a9\uf0d7m) \u2022 (1609 m) / (3.519 x 10-6 m2) R = 7.8 \uf057 ( ohm)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
