The leads from a ohmmeter are attached to the leads of the opposite ends of an AC motor stator field coil. If a reading of infinity is obtained, what does this indicate?

Correct Answer: Option D — open field coil

An infinite resistance reading (open circuit) on an ohmmeter connected across opposite ends of a stator coil signifies a complete break in the metallic conductor path. IEEE 45 insulation and continuity testing guidelines mandate immediate isolation and repair or rewinding.
