A lightning conductor installed in a building
A lightning conductor installed in a building
- A. does not allow the lightning to fall on the building
- B. repels the lightning
- C. forces the lightning to fall in an area where there are no buildings
- D. conducts electric charge to the ground when lightning strikes the building
Step-by-step solution
A lightning conductor is a metal rod mounted on a building and connected to the ground through a low-resistance wire. Its purpose is to conduct the huge electric charge from a lightning strike safely to the earth, preventing damage to the building. It does not prevent or repel lightning, nor does it redirect it to empty areas.
