What does a ground polarity tester indicate?

• A. If the device is compatible with the computer
• B. If a steady amount of voltage is coming through an outlet
• C. If the battery needs to be replaced
• D. If the computer is functioning properly

Answer: (B)

A ground polarity tester is designed to check the wiring of electrical outlets, specifically to determine if there is a proper ground connection and whether the polarity is correct. This means it checks if the live, neutral, and ground wires are connected in the expected configuration, which is crucial for safety and functionality. When an outlet is correctly wired, it ensures that a steady amount of voltage is supplied, minimizing the risk of electrical shock or damage to connected devices. This device does not determine compatibility with a computer, battery status, or overall computer functionality; rather, its primary role is to ensure that the electrical current flowing through an outlet is properly grounded and does not present a hazard. Thus, indicating a steady amount of voltage from a correctly functioning outlet aligns perfectly with the purpose of a ground polarity tester.
