Question

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?

Answer 1

The electrician should use copper because it has the highest conductivity and the lowest resistance among the materials listed.
