Thanks for the clarification as to how the harmonics exaggerates, I think I get it: So, the secondary voltage is the derivative of the primary voltage, and because the higher order harmonics have a greater rate of change than that of the fundamental, those higher order voltage components are larger in the secondary, compared to that of the fundamental component in the secondary voltage.jim hardy said:so e = L d(V/R) dt = L/R dV/dt and that's differentiation. Each harmonic gets exaggerated by its order.
jim hardy said:I drew a parallel - your example differentiated using capacitance, my example differentiated using inductance.

jim hardy said:That's exactly what i hypothesized to explain your observed current wave.
What experiment could you propose to test that hypothesis?
What did you conclude from the waveform ?

Plainly speaking, I was trying to be reminded of what it was that I'd previously said, which spurred on your example, which you gave as a parallel.jim hardy said:?? Expectations ?
