Lightning conductor on the outside of a tall tower. The conductor (green) protects the building from lightning strikes by providing a path of least resistance for the current to flow to earth. It consists of a metal rod at the top of the tower and a strip of metal running to down the side of the building to a plate buried in the ground (not seen). The conductor is made from a metal with a very low resistance,usually copper | |
