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 0.753 ?. The resistivity of nichrome is 1.00 10-6 ? · m and its density is 8.31 103 kg/m3.
(a) What length of wire do you end up with?
m
(b) What is the diameter of the wire?
mm
