Grounding is an electrical connection to ground (the earth).

• A. GFCI
• B. Grounding
• C. Insulator
• D. Conductor

Answer: (B)

Grounding is the intentional connection of electrical systems to the earth to provide a low-resistance path for fault currents and a stable voltage reference. This helps protect people and equipment by allowing faults to be cleared quickly and reducing shock risk. The other options describe different concepts: a GFCI is a protective device that trips when it detects an imbalance between hot and neutral currents, not the earth connection itself; an insulator resists the flow of electricity and is used to keep conductors from contacting each other or something you don’t want energized; a conductor is any material that can carry current, but it doesn’t specify the earth-ground connection that grounding provides.
