    I think maybe it should have been drafted as a definition.
    What? "Un-sine-wavy"?

      There are a number of applications where AC or DC is "chopped", producing something more like a square wave. This is done because the width of the pulses can easily be controlled by a circuit (vs. controlling the amplitude), resulting in efficient control over the average power delivered to the load. This is a very common practice for controlling the brightness of LEDs, though it also works with typical incandescents, as well.

        You can easily find richer harmonic loads with an averaging meter compared to a meter that's true RMS, but that's old school compared to what you can see with a scope
        Old and in the Way.......

          No, the new section I quoted. It looks like a definition, sort of; only it's not in the xxx.2 section of it's article, and it's wording is poor, IMO.
