Which consequence occurs when one phase conductor breaks in a three-phase induction motor under load?

💡 Explanation

When a phase conductor breaks, single-phasing occurs because the motor operates on only two phases, reducing torque capacity while drawing significantly increased current on the remaining phases, producing an unbalanced magnetic field. Therefore, reduced torque and increased current result, rather than balanced operation or complete shutdown, which would require different fault conditions.
