Grounding is a crucial concept in electrical systems that involves creating a path for electric current to reach the earth. This practice is essential for safety and functionality within electrical installations.

When electrical systems are grounded, excess electricity—potentially from faults, lightning strikes, or static discharge—is directed safely away from equipment and personnel into the ground. This helps prevent electrical shock, reduces the risk of fire hazards, and protects equipment from damage caused by overvoltages or surges. Additionally, grounding serves to stabilize voltage levels within an electrical system by providing a common reference point.

The other options do not accurately describe grounding. Insulating electrical cables refers to preventing unintended current flow, establishing power among circuits is about distributing electrical energy, and storing electrical energy pertains to devices like batteries or capacitors, which are unrelated to the primary function of grounding.
