Question

Which type of material must be used for the lightning rods?

Answer 1

Lightning rod:

1. A device is implemented throughout the construction of structures to protect them from the effects of lightning.
2. A lightning rod's aim is to ensure that when lightning struck, the electric current has been carried away from the building and securely transferred to the earth.
3. The rod would be $2\mathrm{cm}$ in diameter and will be attached to a length of copper or aluminum cable or wiring.

Therefore, lightning rods are made from the copper or aluminum metal rod that is attached to the roof of a building.
