Question

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

• A. Ductility
• B. Colour
• C. Electrical conductivity
• D. Solid state

Answer 1

The correct option is B

Colour

Out of the mentioned properties, only the colour of copper is not responsible for it to be used as electrical conduction wires. Colour does not play any role in the electrical conductivity of a metal.

All the other properties such as ductility (the ability of metals to be drawn into wires), electrical conductivity (good conductor of electricity) and its existence as a solid, are responsible for copper to be used as electrical conduction wires.
