The resistance of a copper wire can be calculated by the following formula: Resistance (in 1) = Where p is the resistivity of the material at room temperature (20°C), l is the length of the wire in feet, and A is the cross section area of the wire in CM (circular mil). If the resistivity of the copper wire is 1.723x10-62 CM, what will be the length of the wire if its resistance is 12 Q and a cross section area of 320 CM?

Question
pxl The resistance of a copper wire can be calculated by the following formula: Resistance (in N): A Where p is the resistivity of the material at room temperature (20°C), l is the length of the wire in feet, and A is the cross section area of the wire in CM (circular mil). If the resistivity of the copper wire is 1.723x10-62-CM, what will be the length of the wire if its resistance is 12 2 and a cross section area of 320 CM?
