Question

define a lightning rod

Answer 1

Explanation:

a metal rod or wire fixed to an exposed part of a building or other tall structure to divert lightning harmlessly into the ground.

Answer 2

• A lightning rod  or lightning conductor  is a metal rod that is attached to a structure to protect it against lightning strikes.
• If lightning strikes the structure, it will strike the rod and be carried to ground through a wire, rather than going through the structure, which might cause a fire or electrocution.
• Finials, air terminals, and strike termination devices are several names for lightning rods.

• A single component of a lightning protection system is a lightning rod.
• To execute its protective role, the lightning rod has to be connected to the ground.
• The fact that all lightning rods are constructed of conductive materials like copper and aluminium is the most common feature.
• The most often utilized materials in lightning protection are copper and copper alloys.
