psu ground electricity produces voltage?
I sware i was preparing for electrolysis experiment with my psu and i touched metal case of psu with my hands wet, and it was zapping me with electricity but not to high..........why? P.S: I used grounded cable everything is okay with ground in house, Before when i used it and touched it with dry hands it didnt zap me. I used it always before. But why isnt ground 0V.
