Superposition is not a cause????


Superposition *IS* addition of phasors.

Like addition, superposition is a mathematical operation. There is
without question a mathematical result to most mathematical
operations. But what does this operation itself actually cause in our
case? A physical result has been obtained, but what is its exact
cause? I don't think 'addition' is the best answer.
