I got a mess of components at an auction a couple weeks ago, including an unmarked box of unmarked bridge rectifiers. They're about 1" square & 1/4" high if that makes a difference in terms of an input voltage for testing. I don't know if there are ANY inferences that can be made from size, shape or color. The bottom has the typical one blade that's oriented perpendicular to the other three.
What is the best way to figure out what I've got? I'm not a big fan of the "if it smokes, that's too much voltage...back off a titch and see if the next one smokes" method.
UPDATE: I found a scribbled note in a box of capacitors marked "40/50v Rect", and sure enough, they all test in that range. Now I've just gotta figure out what to do with 'em. Amperage experiments coming up next, but I'm at least confident that I'm starting from a place where nothing will explode. Too much. :)
