Answer 1

Answer:

A Lightning rod without earthing is as good as any other conductor laying stray in open. If its not earthed then it wont work at all. There is nothing very fancy about the whole process. You need to connect both ends of a circuit to make current flow. An improper grounding connection can cause disaster sometimes as the lightening may find another route like plumbing to reach to the ground, which will produce the same effect as that of a lightning striking any building and can result in fire. Even simple grounding is not advisable for such a system. The area at the place of grounding is treated with saline water to increase conductivity.

Answer 2

Answer:

• A lightning rod (US, AUS) or lightning conductor (UK) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it will preferentially strike the rod and be conducted to ground through a wire, instead of passing through the structure, where it could start a fire or cause electrocution. 

• Taller buildings are in greater danger because lightning always strikes the thing which is tallest in the area and has the capacity to enable earthing. Taller buildings are more closer to the clouds. The buildings have metallic poles and structures which provide a low resistance path for the electric discharge .
