Which metal is a poor conductor of electricity?

Options

A. Copper
B. Silver
C. Lead
D. Iron

Answer

To determine which metal is a poor conductor of electricity among the options given (copper, silver, lead, tin), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Metals**: The metals provided in the options are copper, silver, lead, and tin.

2. **Understand Electrical Conductivity**: Metals are generally good conductors of electricity, but they have varying levels of conductivity. The better a metal conducts electricity, the lower its resistance.

3. **Rank the Metals by Conductivity**: Based on known properties of these metals, we can rank them in terms of their electrical conductivity:
- Silver: Best conductor
- Copper: Second best conductor
- Tin: Moderate conductor
- Lead: Poor conductor

4. **Conclusion**: From the ranking, we can conclude that lead is the metal that is a poor conductor of electricity compared to the others listed.

### Final Answer:
Lead is the poor conductor of electricity among the given options.
