If a ground exists in a conductor you are testing, what reading will you get on an ohmmeter?

If a ground exists in a conductor you are testing, what reading will you get on an ohmmeter?

• A. Zero
• B. Infinity
• C. A variable value
• D. Continuity

Answer: (A)

When testing a conductor with an ohmmeter, if a ground exists, it indicates that there is an unintended connection between the conductor and the ground. In this scenario, the ohmmeter will measure a very low resistance, ideally close to zero. This low resistance reading means that current can flow easily through the conductor to ground, resulting in a reading that suggests no resistance to the flow of electricity. Additionally, a reading of zero signifies a direct path for current, which confirms that the conductor is effectively shorted to ground. This is critical in electrical testing as it indicates a potential safety issue that needs to be addressed. Recognizing this condition allows for corrective measures, ensuring that the system is safe and functioning properly.
