Question:medium

Which of the following is a poor conductor of electricity?

Show Hint

Electrical conductivity order: Ag>Cu>Au>Al>Mg>Zn>Fe>Pb.
Lead is a poor conductor, hence used in batteries (not for wiring).

Show Solution

The Correct Option is A

Solution and Explanation

To determine which among the given options is a poor conductor of electricity, we need to understand the electrical conductivity properties of these metals.

  1. Copper (Cu): Copper is one of the most widely used metals for electrical wiring due to its excellent conductivity. It facilitates the easy flow of electric current.
  2. Silver (Ag): Silver actually has the highest electrical conductivity of any metal, even higher than copper. It is often used in specialized electrical components.
  3. Aluminum (Al): Aluminum is also a good conductor of electricity, although not as good as copper or silver, it still supports efficient electric current flow and is used in overhead power lines due to its light weight.
  4. Lead (Pb): Lead is significantly less conductive than the other metals listed. It has high resistance and is considered a poor conductor of electricity compared to the alternatives.

The reason behind lead's poor electrical conductivity is due to its electronic structure and the relative positioning of its electrons, which doesn't allow for easy flow of electric current.

Thus, based on the analysis of electrical conductivity of the given metals, the correct answer is that Lead (Pb) is the poor conductor of electricity.
