What is the purpose of a grounding wire in electrical devices?

• A. To enhance electrical flow
• B. To prevent electric shock by providing a safe path for excess current
• C. To improve device performance
• D. To reduce energy consumption

Answer: (B)

The grounding wire in electrical devices serves a critical safety function by providing a reliable path for excess electric current to follow in the event of a fault or malfunction. If a device experiences an electrical fault, such as a short circuit, the grounding wire facilitates the quick diversion of excess current away from the user and into the ground. This minimizes the risk of electric shock, allowing the current to bypass the person who might be touching the device. Grounding is essential for protecting both people and equipment. It is designed to prevent hazardous situations from occurring, making it a fundamental aspect of electrical safety standards. While enhancing electrical flow, improving performance, or reducing energy consumption may be beneficial in other contexts, these reasons do not accurately describe the primary function of a grounding wire. The grounding wire is specifically about safety and protection from electrical hazards.
