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?
(1 point)
• iron
• gold
• copper
• carbon steel
The electrician should use copper.
Copper has the highest conductivity value out of the given options, meaning it is the most effective at conducting electricity. Additionally, copper has the lowest resistance value, further emphasizing its suitability for wiring a house.
