power supplies

by "H. Dixon" <huwdixon@[EMAIL PROTECTED] > Jul 28, 2008 at 07:02 AM

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.
