Ooops. Yeah, you are right, my bad. Thanks for the posts.Your V-A characteristics looks good. But why you reverse the voltage polarity in the second pic? Why not 15.3V on first quadrants and 1.4V on the third quadrants ?
These aren't batteries and the diodes aren't generating 6.3V and 9V. wI don't understand the circuit:
Why 6.3 V can be in parallel with 9V? Is this a short circuit?
