How do lighting rods protect buildings from lighting?

In: Physics [Edit categories]

Answer:

Lightning will follow the path of least resistance - the tallest objects and more conductive materials. Because the rod is placed to be higher up than the next highest point of the building, lightning will strike the rod and not the building. Because the rod is more conductive, the lightning can be channeled down the length of the building to be safely grounded.
