Question

Select the correct safety measure to protect a building from lightning.

• A. Concrete walls
• B. Lightning conductor
• C. Multiple TV antennas
• D. Metallic water pipes

Answer 1

The correct option is B Lightning conductor

A lightning conductor is a device used to protect buildings from the effect of lightning. A metal rod is installed on the roof of the building such that the upper tip of the rod is higher than the highest point of the building. This rod is then connected to the ground through a conducting wire which provides an easy route for the transfer of electric charge from the sky to the ground while not harming the building.
