What is the phase relationship between current and voltage for reactive power?
They are out of phase
They are in phase
They are 90 degrees out of phase✓الإجابة الصحيحة
They are 45 degrees out of phase
الشرح
Reactive power is the portion of power that flows back and forth without being consumed, and it exists only where the current is in quadrature with the voltage. Pure inductance and pure capacitance both produce that 90-degree relationship.
