What is the function of a lightning conductor? - Leaving Cert Physics - Question i - 2016

The primary function of a lightning conductor is to provide a safe path for lightning to discharge into the ground. It effectively

1. Earths the Building: The conductor directs the electrical charge from a lightning strike away from the structure, minimizing the risk of fire and damage.

2. Protects Structures: By channeling the energy of a lightning strike, it protects buildings and occupants from potential harm.

3. Point Discharge: The conductor provides a point of discharge for the lightning, which can be achieved through a metal rod that is installed at the highest point of the structure.
