When I measure the voltage at a selection of wall transformers that I have laying around, I see that the actual voltaged measured is greater than the output voltage printed on the transformer.
ex. a +12VDC transformer outputs +18VDC, a +9VDC outputs +14,8VDC and a +4,5VDC ouputs +5,07VDC. Why does it outputs more voltage than rated? And why is it printed a lower voltage on the transformer than it actually outputs?
Cheers!
