Generally, yes, but there are other ways it could cause severe damage, too.Doesn't the current need to reach your heart to kill you?
Since this a line powered device, it would be prudent to look for possible "leakage" currents from the line through the case or any of the output terminals to ground. "If" the person was rendered unconsciousness, it's more likely from a high voltage AC source than 9VDC...just from my experience in Biomedical Electronics service.has your investigation determined the current path?
I think others may have commented on the inaccuracy of this, but I think this is lore. This paper, entitled 9 Volt Battery-SHORT CIRCUIT ANALYSIS, reports short circuit current of 4 to 5 amps for a short time. If the current is limited to a few milliamps, it is by the resistance of the wet tongue, and not by the battery's internal resistance.As strantor said, a 9 volt battery can not source nearly as much current as a lead acid car battery can. Licking a 9 volt battery won't cause more than a couple of milliamps to flow through your tongue. Licking a car battery could easily allow a lot more current to flow, and thus cause a lot more damage.
As do I...I stand corrected
