Step 1
Step 1: The resistance of a wire is given by the formula: $$R = \rho \frac{L}{A}$$ where: * $R$ is the resistance in ohms * $\rho$ is the resistivity in ohm-meters * $L$ is the length of the wire in meters * $A$ is the cross-sectional area of the wire in square Show more…

A 52.0 g sample of a conducting material is all that is available. The resistivity of the material is measured to be 13 X 10-8 Ω · m, and the density is 7.99 g/cm3. The material is to be shaped into a solid cylindrical wire that has a total resistance of 1.5 Ω. What must be the diameter of the wire? 0.978 mm 1.32 mm 0.112 mm 0.324 mm
