SUMMARY
The resistivity of nichrome wire is established at 1.1 micro ohm meters. To achieve a resistance of 1.0 Kohm using a wire with a diameter of 0.079 mm, a length of approximately 4.5 meters is required. The formula used is R = resistivity x length / area, where the area refers to the cross-sectional area of the wire. The cross-section is circular, and the radius must be converted to meters for accurate calculations.
