If an ohmmeter reads zero between two wires, which statement is correct?

If an ohmmeter reads zero between two wires, which statement is correct?

• A. The wires are completely isolated
• B. There is infinite resistance
• C. They are fused
• D. There is zero resistance between them

Answer: (D)

When an ohmmeter shows zero between two wires, it means there is a direct, very low-resistance path connecting them. In other words, the two points are effectively shorted—they’re touching or connected by a conductor with negligible resistance. If there were no connection, you’d expect the reading to be infinite or show “OL.”
