If an ohmmeter indicates zero resistance when measuring the contactor coil, it means that the coil is _________.

A Short circuit.

A resistance reading of zero implies that there is no resistance in the coil, suggesting a direct short circuit. In electrical circuits, a short circuit occurs when current flows along an unintended path, bypassing the normal load. It's important to address and correct short circuits as they can lead to malfunctioning equipment, overheating, and other safety hazards.
