Well, er, not to me. Here's the video:
http://www.youtube.com/watch?v=xkKPfhQgEVk The generator coil is shorted; but, he claims the step function represents energy. The input pulses are also shown; and, Sean also calls these energy. I am totally confused (which is likely the intent). Energy is measured in watt-seconds; but, McCarthy does not explain the scope traces in adequate detail to verify this is what he measures. Shorting the generator coil makes no sense. Why not have a 1 Ohm precision resistor so that you can measure current and voltage. You could then show (in 4 channels) current and voltage in against current and voltage out. Since this is a digital scope, you could provide CSV tables with this data so that anyone can run the numbers. T
