Which outcome occurs when single phasing in a three-phase motor due to an open circuit?

A)Increased winding current and overheating
B)Balanced torque and stable rotation
C)Reduced overall harmonic distortion
D)Improved motor power factor and efficiency

💡 Explanation

Increased winding current happens in single phasing due to the negative sequence impedance. The **negative sequence impedance** causes uneven current distribution; because the motor attempts to maintain power, this drives up the current through the remaining phases; therefore, overheating, rather than balanced torque as in normal operation.
