SOLUTION: If #28 copper wire (which has a diameter of 0.0126 inch) has a resistance of 66.17 ohms per thousand feet, what length of #28 copper wire will produce a resistance of 33.5 ohms? Us

Question 652399: If #28 copper wire (which has a diameter of 0.0126 inch) has a resistance of 66.17 ohms per thousand feet, what length of #28 copper wire will produce a resistance of 33.5 ohms? Use the fact that the resistance of a wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross sectional area

66.17/1000=33.5/x
66.17x=33500
x=33500/66.17
x=506.27ft
