An electrician is trying to decide which kind of material to use to wire a house.
carbon steel: conductivity = 1.43 × 10−7, resistance = 1 × 1010
copper: conductivity = 5.96 × 107, resistance = 1.68 × 10-8
gold: conductivity = 4.11 × 107, resistance = 2.44 × 10−8
iron: conductivity = 1 × 107, resistance = 1.0 × 10−7
Based on this information, which material should the electrician use?

Copper has the highest conductivity and lowest resistance compared to the other materials listed. This means that copper would be the most efficient material to use for wiring a house, as it will allow for better flow of electricity and less energy loss.
