Hi.
I have two PCs and if I want to connect one of them to stereo i have to
plug the jack from one to the other. I made it easy by using extension cord.
Few times i got not so small electric shock when I simultaneously touched both
PCs mass.
Today I actually measured the current and voltage between two masses using
rectifier + cap. I got 55V DC (when rectified) and 8mA short circuit current.
In my house I don't have earth so power cord's earth is not connected to anything.
I want to ask why do they put capacitors between hi voltage mass and
lo voltage mass inside the PSU.
I assume they responsible for this leak current or could it be somecind of malfunction?
I also tried to unplug the wall plug and reverse it, but same result.
I can connect two earth together but then that 8ma will be flowing somewhere.
Many thanks.
Edit:
When I press (audio)cord from PC1 against the PC2 (metal) housing i hear chirping/hissing sound
from that small spark so I conclude it is high frequency.
