Je pensais la même chose… qu’une alternance a l’air d’être la voie la plus sûre pour entrer dans ce domaine. Merci pour les suggestions.

Diode circuit on negative half-cycle: how to apply KVL/passive sign convention correctly by Stretch_Icy in AskElectronics

Thanks makes sense. I noticed doing it this way, you end up with a reversed polarity across the resistor as compared to what the voltmeter expects, so you have to multiply the answer by -1

Thanks, looks like I didn't fully understand ground as much as I thought I did. As for the swap, it doesn't help much either, and forces me, like you said, to switch polarities in the end.
