Lightning rods protect buildings by providing a path of least resistance for lightning to follow, safely directing it into the ground and away from the structure, preventing damage and fire.

MCQs
1. Where is a lightning rod usually installed on a building?
A) On the ground next to the building
B) On the highest point of the building
C) Inside the building
D) Underneath the building
Answer: B) On the highest point of the building
Explanation: Lightning rods are placed at the highest point to intercept the lightning strike and safely conduct its electrical charge to the ground.
2. What happens when lightning strikes a building equipped with a lightning rod?
A) The building catches fire
B) The lightning is absorbed by the rod
C) The lightning is directed safely to the ground
D) Nothing happens
Answer: C) The lightning is directed safely to the ground
Explanation: The lightning rod intercepts the lightning strike and safely directs its energy into the ground through a conductive path, preventing damage to the structure.
3. Why is it important for the lightning rod to have a connection to the ground?
A) To keep the rod stable
B) To protect the ground
C) To dissipate the lightning’s electrical charge safely
D) To make the rod look taller
Answer: C) To dissipate the lightning’s electrical charge safely
Explanation: The ground connection is crucial for allowing the electrical charge from the lightning to disperse safely into the earth, preventing damage to the building and reducing the risk of fire.
4. What material is commonly used to make lightning rods?
A) Wood
B) Plastic
C) Metal
D) Glass
Answer: C) Metal
Explanation: Metal is used because it is a good conductor of electricity, allowing the lightning’s electrical charge to be efficiently and safely directed to the ground.
5. Can lightning rods protect the building from all types of damage during a storm?
A) Yes, from all types
B) No, only from lightning
C) Yes, including floods
D) Yes, including earthquakes
Answer: B) No, only from lightning
Explanation: No, lightning rods cannot protect buildings from all types of damage during a storm. They primarily mitigate the risk of lightning-related damage but do not offer complete protection against other storm-related hazards like wind or water damage.
