Question

Which of the following property is not responsible for copper to be used as electrical conduction wires?

• A. Ductility
• B. Color
• C. Good conductor of electricity
• D. It is solid

Answer 1

The correct option is B

Color

The correct option is (B):

Explanation for the correct answer:

Color:

1. All the metals have some amount of resistivity to the electric currents, that's why they require a power source to just push the current through.
2. So, the lower the level of resistivity , the more electrical conductivity will a metal have.
3. As the Copper metal has low resistivity therefore it is an excellent conductor.
4. Also as the Copper does not rust and will also produce a greenish patina known as Copper oxide.
5. Unlike the rust, however the covering actually protects the metal from the further corrosion and so doesn't interfere with the conductivity.

Explanation for the incorrect answers:

Option (A):

Ductility:

1. It is actually the physical property of the metal which is generally the ability of the material to be drawn into the thin wires without the fracture.
2. And this property is responsible for copper to be used as electrical conduction wires.
3. Hence, this option is incorrect.

Option (C):

Good conductor of electricity:

1. Copper is a good conductor of electricity.
2. And because of this property, it is capable for the flow of electrons and current throughout.
3. Hence, this option is incorrect.

Option (D):

It is solid:

1. Copper is solid and hard in nature.
2. Ans solid metals are basically the best conductors for the electricity as well as heat too.
3. Hence, this option is incorrect.

Therefore, the correct option is (B): Color.
