Scenario: You work as a materials engineer and have been tasked with investigating issues with substandard cables manufactured by your company. These cables are made from copper with varying cross sectional areas depending upon their current carrying capacities. Cables are not meeting the required voltage drop characteristics compared to theoretical values, but your manager is not sure of the reason for this and has hypothesised that this could be due to impurities within the copper itself. It has been suggested that the resistivity of the copper used should be investigated. With reference to the attached samples picture: A) what is the actual resistance of the cable samples. given that you multiply the cross sectional area by strand number. B) what is the actual resistivity of each sample.
