Expert Answer
The power factor varies between 0 and 1.
Power factor (PF) = cos Θ
Where,Θ is phase angle between voltage ad current
For purely resistive circuits, phase angle between voltage and current is zero thus, power factor is 1 and for purely reactive circuits, phase angle between voltage and current is 90 degree thus, power factor is 0
