Except, you also need to keep in mind the internal resistance of your power source. If that one is higher enough than the human body resistance, you could have a very high voltage which is actually not very dangerous.
- stordoff 11y agoI assume this is the reason I was able to safely use a 5000V power source in school, despite being shocked multiple times (IIRC, the maximum current it would give, even if you shorted the output terminals, was 3mA. Our teacher at the time did initially insist on wearing latex gloves, but they were discarded once we realised the current would just arc through the gloves and leave holes in them). You do start to see some odd effects at those voltages though - I recall holding one of the output plates for ten minutes or so, without realising the supply was on. Didn't really think much of it, until I realised I could hold my hand over a piece of tin foil (roughly 1cmx1cm) and it would be attracted to my hand from 2-3cm away (that persisted for five minutes or so).
