I have got a 12V dc power suppy for external hard disc. when i was connecting the harddisc USB connector to the computer i got a shock. On checking I found that power supply out put gives 12V dc and 25V ac. However on interchanging the the terminals it shows only dc and no ac.
It is puzzling to me can any one throw some light :?
