A 41.4 gram sample of a conducting material is all that is available. The resistivity of the material is measured to be 1.14 × 10-7 Ω•m and the density is 7.69 g/cm3. The material is to be shaped into a solid cylindrical wire that has a total resistance of 1.78 ohm.
A) Compute what length is required?
B) Compute what will be the diameter of the wire?
