An electrician is trying to decide which kind of material to use to wire a house.
⚫ carbon steel: conductivity = 1.43 x 10-7, resistance = 1 × 1010
⚫ copper: conductivity = 5.96 x 107, resistance = 1.68 x 10-8 • gold: conductivity = 4.11 x 107, resistance = 2.44 × 10-8
⚫iron: conductivity = 1 x 107, resistance = 1.0 × 10-7
Based on this information, which material should the electrician use?
(1 point)
O carbon steel
O gold
O iron
copper
1 answer
The electrician should use copper as it has the highest conductivity and the lowest resistance out of the given options, making it the most efficient material for wiring a house.
