As part of a class project you are given 0.900 g of nichrome and asked to fabricate a wire with uniform cross-section. You use up 95% of the nichrome and make a wire with a resistance of 0.693 2. The resistivity of nichrome is 1.00 x 10-6 2. m and its density is 8.31 103 kg/m. (a) What length of wire do you end up with? 8.444 How is the volume of metal used related to the length and cross-sectional area of the wire? How is the resistance related to the length and cross-sectional area of the wire? m (b) What is the diameter of the wire? mm As part of a class project you are given 0.900 g of nichrome and asked to fabricate a wire with uniform cross-section.
