Theory & DesignCâu 81 / 110
In a balanced wye (star) three-phase system, the line current is:
a.Equal to the phase current
b.1.732 times the phase current
c.0.577 times the phase current
d.2 times the phase current
Giải thích
In a wye connection the same conductor carries phase and line current, so line current equals phase current.
