I have a nice and neat little PSU with a fuse from a DVD player, it outputs +/-12, gnd and +/-5 so 24 , 17 and 7 as well.
The PCB had a 2 prong AC plug, probably with one bigger than the other. And on the PCB there is a place where a 3rd ground prong would be screwed on like on my printers PSU , and it is copper traced to several things.
I soldered on a 3 prong cable/plug but never hooked up the ground prong, what would happen if I did?
Would it be bad or good? I've done high school physics and 1st year university physics, so there's a mountain I still need to learn now that I'm back into electronics.
Is it that 1 of the 2 prongs acts as ground, so don't hook up the 3rd prong, its already safe enough to use (I was using it in a flashlight, but now I have a LAMP hung from the ceiling!, so I can use it for a bench PSU again)
