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
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.
To determine which material the electrician should use to wire the house, we need to consider the conductivity and resistance values of each material. The material with the highest conductivity and the lowest resistance would be the most suitable choice.
Comparing the conductivity values:
- Carbon steel: 1.43 x 10^-7
- Copper: 5.96 x 10^7
- Gold: 4.11 x 10^7
- Iron: 1 x 10^7
Comparing the resistance values:
- Carbon steel: 1 x 10^10
- Copper: 1.68 x 10^-8
- Gold: 2.44 x 10^-8
- Iron: 1 x 10^-7
Based on this information, the copper material has the highest conductivity and the lowest resistance. Therefore, the electrician should use copper to wire the house.
To decide which material the electrician should use, we need to consider the conductivity and resistance of each material.
Conductivity is a measure of how well a material allows electric current to flow through it. Higher conductivity means better flow of electric current.
Resistance is a measure of how much a material opposes the flow of electric current. Lower resistance means less opposition to the flow of electric current.
To determine which material is the best choice, we need to compare the conductivity and resistance values for each option.
Option 1: Carbon Steel
- Conductivity: 1.43 x 10-7
- Resistance: 1 × 1010
Option 2: Copper
- Conductivity: 5.96 x 107
- Resistance: 1.68 x 10-8
Option 3: Gold
- Conductivity: 4.11 x 107
- Resistance: 2.44 x 10-8
Option 4: Iron
- Conductivity: 1 x 107
- Resistance: 1.0 x 10-7
We can see that copper has the highest conductivity value among the options, indicating that it allows for better flow of electric current. Additionally, copper also has the lowest resistance value, indicating less opposition to the flow of electric current.
Therefore, based on this information, the electrician should use copper as the material for wiring the house.
