Hello, i am trying to understand the concept of active /reactive /complex power and am having some trouble understanding how the reactive powere 'oscillates back and forth between inductor and source'. Ok, lets say i have a pure inductive load, i know that the power consumed is 0, and i understand the mathematics which prove this. But i also know its not 'actaully' 0, the power, reactive power, is continuously travelling back and forth between source and load. But how? Is it because of the voltage across the inductor causing a magnetic field to be created and when there is no more voltage drop across the inductor, the magnetic field collapses releasing this power it consumed in the first place? If so how does it release this power? is it due to the change of magnetic field (it collapsing) which induces current in the circuit? help please!
