What does a low reading on an ohmmeter indicate?

• A. No continuity
• B. Good connection
• C. Open wire
• D. Short circuit

Answer: (B)

A low reading on an ohmmeter typically indicates a good connection or low resistance within the circuit being tested. When resistance is low, it suggests that electricity can easily flow through the component or connection, which is desirable for most electrical systems. This scenario indicates that the wiring or part being tested is in good condition without excessive resistance that could hinder current flow. In contrast, the presence of no continuity would reflect a high reading on the ohmmeter, potentially indicating a break in the circuit. An open wire would also show high resistance or infinite resistance, signaling a disconnection in the circuit. Lastly, a short circuit may also lead to a low reading, but typically it would indicate such a condition is problematic rather than reflective of a good connection, as it often suggests unintended connections that could be dangerous or damaging. This differentiation is important in diagnosing issues within electrical systems.
