How does a grounding rod work to protect against electrical surges and ensure the safety of a building's electrical system?

A grounding rod is a metal rod buried in the ground near a building. It works by providing a path for excess electrical energy to safely dissipate into the ground, preventing it from damaging the building's electrical system. When there is a surge of electricity, the grounding rod redirects the excess energy away from the building, reducing the risk of electrical fires and ensuring the safety of the electrical system.
