I'm more than happy to learn from your expertise.
To be honest, I wouldn't ask the question at all - because it's such a pointless one. But, if I HAD TO ask it, I would specify the exact make and model of the two PSU's, and provide the circuit diagrams of them both.
Or (even better), I would specify batteries instead of power supplies, and inform you that they are theoretically perfect batteries - which is what a PSU is trying to emulate (and failing!).
I imagine I'm like most people on these forums?, I've had actual experience in exams of un-answerable questions, badly written by people who don't have a clue!.
