A metal which is poor conductor of electricity is

• A. Zinc
• B. Aluminum
• C. Tungsten
• D. Iron

To determine which metal is a poor conductor of electricity among the options provided—Zinc, Aluminum, Tungsten, and Iron—we need to consider the electrical conductivity of each metal. Conductivity refers to how easily electrons can flow through a material, and metals generally have high conductivity due to their free-moving electrons.

Examining the Options

Let's break down the conductivity of each metal:

• Zinc: While not the best conductor, zinc does have decent conductivity, making it suitable for various applications, including galvanization.
• Aluminum: Known for its excellent conductivity, aluminum is widely used in electrical wiring and components.
• Tungsten: This metal has good conductivity and is often used in applications requiring high melting points, such as light bulb filaments.
• Iron: Iron is a better conductor than zinc but is still less conductive than aluminum and tungsten. However, it is not classified as a poor conductor.

Identifying the Poor Conductor

Among these options, zinc is the least conductive, but it is not typically categorized as a poor conductor in the same way that non-metals are. However, if we consider the context of the question, we might interpret "poor conductor" as the metal with the lowest conductivity compared to the others listed.

Conclusion

In this case, the answer would be Zinc, as it has the lowest conductivity among the four metals mentioned. While it is still a conductor, it does not perform as well as aluminum, tungsten, or iron in terms of electrical conductivity.
