In a wye wired system, the relationship between line current and phase current is that they are in what kind of relationship?

In a wye (Y) wired system, the line current and phase current are not in a series relationship but are actually equal to one another. Each phase of the system carries the same current as the line current. This is due to the way connections are made: in a wye configuration, each phase winding connects to a common neutral point, and the line currents directly correspond to the phase currents without any additional resistance or impedance that would create a series relationship.

When considering the three-phase system characteristics, you would observe that in a wye connection, the line current entering the system does so at the same magnitude as the current flowing through each individual phase. Therefore, the correct relationship is that line current equals phase current, emphasizing their equality rather than any other relationship like series or parallel.
