I've got a couple of AC/DC power adapters that went to various things that are no longer around. They have various output voltages and currents. Would these be useful as a power supply into my breadboard? One of these is 12VDC but 1.2Amps. The others are all in the mA range.1.2A seems high for experimenting...
I read the voltage on the "12vdc" one and it was reading 15.5 vdc. Is that typical - for the actual to be higher than what is listed? Also I noticed that the measured voltage moved around a bit over time by a few tenths of a volt. Does that mean it's shaky/going bad?
Sorry - lots o' questions but I'm without PS at the moment...the one I was building from scratch is on hold as I popped the capacitors. Now I know which axial end is which.
