For a balanced three-phase load, the total power is equal to
A) root 3 x line voltage x line current
B) root 3 x line voltage x line current x power factor
C) root 3 x phase voltage x phase current
D) root 3 x phase voltage x phase current x power factor

Question

Quizplus · Accepted Answer

The total power in a balanced three-phase load is given by the formula: P = √3 x VL x IL x cos(φ), where VL is the line voltage, IL is the line current, and cos(φ) is the power factor. This matches choice B.
