When checking resistance on a split-phase motor, common-to-run will be the __________ ohm reading, common-to-start will be the __________ ohm reading, and start-to-run will be the __________ ohm reading.

Question

Quizplus · Accepted Answer

In a split-phase motor, the common-to-run winding has the lowest resistance because it's designed for continuous operation. The common-to-start winding has a higher resistance as it's used briefly for starting. The start-to-run reading combines both windings, resulting in the highest resistance.
