A 50.0 g sample of a conducting material is all that is available. The resistivity of the material is measured to be 11 x 10-8 O m and the density is 7.86 g/cm3. The material is to be shaped into a solid cylindrical wire that has a total resistance of 1.5 O.
a) What length of wire is required?
b) What must be the diameter of the wire?
