If we classify these terms from a professional perspective, then the inductive reactor (inductor) and capacitive reactor (capacitor) are collectively referred to as reactors. The role of Reactors: Because so many different reactors do different things, they can be split into two groups based on how their circuits work: in series and in parallel.
