f the voltage and current differ in phase by π / 2 , then Power factor, cos φ = cos 900 = 0 .
In this case, the current has no power. Such a current is, therefore, called wattless current.
Since this current does not perform any work, this current may also be called idle current. Such
a current flows only in purely inductive or in purely capacitive circuits.
