Pure inductor never consumes power

0 because power factor cos(angle)= cos(angle between voltage and current) and for pure inductor the angle=90 degree. so the value of power factor is zero..

Zero

The current lags behind voltage by 90 degrees in case of a pure inductor 

Therefore the power factor = cos{angle between voltage and current} 

= cos(90) = 0
