What is the resistance per metre of copper wire?
A resistivity of 1 mm2 and a cross-sectional area of 1 mm2, at room temperature (20 degrees C), is called the resistivity of this material
A cross-sectional area of 1mm^2; a 1m long copper wire; the resistance is 0.017 ohms
Pure copper resistivity 0.0175 /m.1.13mm pure copper wire, cross sectional area of 1 mm2,So its resistance is 0.0175 ohms
