But even in this situation, the computer is unlikely to die. Please note - NO 50 volts can be obtained on the computer case. After all, the welder is connected at both ends to one point on the computer. Tales about the capacitance of transformers and the transmission of current through one wire in two directions is not necessary.

If any other grounded computers are connected to the computer who the hell knows where then of course they burn. Now think about what happens when you LOSE your computer! Electricians really like to burn out some neutral wire somewhere. Then, along with it, all household electronics very often burn out... So in this case, when zeroing, the picture turns out to be the same, and if you consider that this very neutral wire has a non-zero resistance... In short, it’s better not to ground at all. Normal land is difficult to find.

And where does the static come from, or where does it go when grounded? :-/ Even If the monitor’s power supply does not remove it, then everything is connected through the computer. It is implied that the monitor is connected to the computer or everything is plugged into one extension cord "PILOT". But the modem seems to work better when grounded, I can’t check. Among users Vicomm modems practiced the method of connecting the Vicommka with one wire to battery, and others to the telephone line. After that they said 2400 trains. And I have not like that at all It worked, but it didn’t seem like it should have. :-/
