WebHence, the average power in a purely inductive or capacitive circuit is zero even though a current is passed through it. This current is called wattless current. Wattful Current At … WebIn other words, wattless current occurs when current flows without power loss, wherein a pure inductor is coupled to an AC circuit. It consists of a reactive component, which is the algebraic sum of the inductive and capacitive reactances. Both reactances obstruct the flow of AC. The resistive components perform two things.
