Silver is a good conductor of electricity and has a higher conductivity than copper, which makes it an attractive material for use as a lightning conductor. However, there are several reasons why silver is not commonly used as a lightning conductor:
Cost: Silver is much more expensive than copper, which makes it a less cost-effective option for use as a lightning conductor.
Corrosion resistance: While silver has a high resistance to corrosion, it can still corrode over time. This can reduce its effectiveness as a lightning conductor and make it more difficult to maintain.
Mechanical strength: Silver is a relatively soft metal, which means it is more prone to mechanical damage than copper. This can make it less suitable for use as a lightning conductor, particularly in applications where the conductor is exposed to physical stress.
Overall, while silver is a good conductor of electricity, it is not typically used as a lightning conductor due to its cost, corrosion resistance, and mechanical strength. Copper is generally considered the most suitable metal for this application due to its balance of conductivity, durability, and cost-effectiveness.
Summary: Mechanical strength,cost and corrosive resistance make COPPER MORE SUITABLE THAN SILVER OR Al
The correct answer is:
Copper
Reasons:
- High electrical conductivity
- High melting point
- Corrosion resistance
- Ductility and malleability, making it easy to shape and install.
silver is the best lightning conductor,but not the most suitable bcs its expensive
so the answer should be cupper
