    But if you don’t actually complete the circuit to ground, then current cannot actually pass through you, only voltage. You’ll feel a tingling. See if you can turn on an LED by connecting its ground lead to your carpet or tile floor.

      Wdym “the current cannot pass through you, only voltage” 😂, bro who taught you this.

      If you don’t exist in the worst case scenario (wet hands, barefoot on wet tiles or sum), you probably have a lot of resistances, skin contact, shoe sole, idk carpet. Since your body has only around 500-1000 ohms (I think) the voltage applied to the body would be way less. If your shoes got 10,000 ohms, they’d get 100 volts and you like 10. This scenario would be 10 milliamps then. Numbers out my ass, but you don’t get “voltage, but no current”. Except if you manage to raise your body’s internal resistance somehow.

      Well seems to me you do complete the circuit. With some 1000 Ohm resistance of your body, plus shoes depending on whether you’re wearing them and how you’re posed, plus whatever your floor provides to ground. Tile sounds ideal, but I’m not so sure about wood.

      I guess floor heating would not be using metal piping, so at least that’s no shortcut. Maybe rebar could be trouble, but probably the wooden flooring shouldn’t be resting directly on the rebar.

      I guess in most normal situations that would be enough resistance. I concede that point.
