2. Consider an aluminium wire with a diameter of 1.07 mm. a. What would be the diameter of a copper wire of the same length with the same resistance? Would it be more or less massive than the aluminium wire and by what factor? The density of copper is roughly 8,960 kgm³. b. What would be the diameter of a graphite wire of the same length with the same resistance? Would it be more or less massive than the aluminium wire and by what factor? The density of graphite is roughly 2,230 kgm³. c. What would be the diameter of an amber 'wire' of the same length with the same resistance? Would it be more or less massive than the aluminium wire and by what factor? The density of amber is roughly 1,096 kg m³.
