Well, the secondary resistance is 26 ohms and the capacitor is 30 mf. I haven't
measured the peak current, since I don't know how to do that! The relay is an
Opto 22 type 240D45; the catalogs I have don't show the peak current rating for
it. But similar relays are rated at much more than 100a peak (e.g., 600a).
Maybe someone has the complete specs on this one?
