I understand completing a circuit to ground or something is lethal. I also know it has something to do with your bodies capacity but why does that kill you
In: Physics
It can’t and you do. For example, birds sit on high voltage power lines all the time without being zapped because they’re not completing a circuit. What you probably are unclear about is that the literal earth itself and anything conductive connected to it can complete the circuit and allow current to flow through your body and into it. That’s why we call it “ground”.
