Analog ohmmeter interpretation: When the pointer on an analog ohmmeter deflects close to zero ohms, what does this indicate about the resistor under test?

Introduction / Context:
Reading an analog ohmmeter correctly is essential for diagnosing component health and wiring faults. The meter's scale is typically non-linear, with zero ohms at full-scale deflection, indicating very low resistance or a short condition.

Given Data / Assumptions:

• An analog ohmmeter is used on a de-energized component.
• The pointer moves near the zero-ohms end of the scale.
• Test leads and internal battery are assumed good and zeroed.

Concept / Approach:
Ohmmeters apply a small internal voltage and measure resulting current to infer resistance. A near-zero reading indicates very high current for a given internal voltage, meaning very low resistance—consistent with a short or near-short path.

Step-by-Step Reasoning:

Verification / Alternative check:
Swap test leads or measure a known-good resistor to confirm meter function. If another meter confirms ≈ 0 Ω, the diagnosis stands.

Why Other Options Are Wrong:

• Overheated: A temperature state, not directly indicated by resistance reading.
• Open: Would show infinite or very high resistance (pointer toward ∞/left).
• Reversed: Polarity is not relevant for passive resistors on an ohmmeter.

Common Pitfalls:

• Forgetting to zero the analog ohmmeter before measurement.
• Measuring in-circuit and reading parallel paths as low resistance; isolate the component if uncertain.
