Question

Quizplus · Accepted Answer

The principle of a lightning rod is to intercept the lightning strike and safely carry the lightning current around the object it protects. This is accomplished through the use of a metal rod or conductor that is placed on top of a building or structure and connected to a grounding system. When lightning strikes the rod, the electrical energy is conducted through the rod and safely into the ground, reducing the risk of damage or injury.
