Comment on So how would you handle this?

  the path of least resistance for the current would be down one connected bolt, then around the top plate, and up the other battery connected bolt, never down the pole, so the ceiling/floor gets heated up, possibly burn

  note: those bolts must be supper long to go from ceiling to floor

    12v is hardly anything. This is not a joke, go put your hands on both terminals of a car battery. You won’t feel a thing.

      12 V is not enough to pass through unbroken skin, yes. But 12V has plenty to pass through some bolts and heat up enough to burn your house down.

      You may be interested in StyroPyro’s video where he wired 100 car batteries in parallel. Still 12V, but huge current capacity.

      still can spin a big truck and/or turn on incandescent bulbs with temperatures in the thousands of degrees

      the internal resistance of lead-acid batteries is in the tens of mili-Ω, the circuit of 2 bolts and one plate/top of the pole would be in the low 100s mili-Ω. lets round up to 200mΩ, power = V•I = V^2•R = 12^2/0.2 = 720W, enough to heat up the top assembly of the pole, and smolder some wood

      That’s true but only because the voltage is low a car battery can pull ~2X the amps in of main it won’t kill you because it can’t connect but if it ever did

    That’s why you connect it directly to main so it doesn’t require a closed loop to create a chemical reaction,.

  It’s rather unlikely that the person touching the pole would provide a path from the pole to ground.

  12V from a car battery doesn’t do much damage. You’d need, I think, 50V or 52V to get through the skin. Now, of course, if someone were to stick it in their mouth or some other area that doesn’t have skin, it’s a different story, then they’d get heavy burn marks on the path the electricity takes. So for safer electrocution, use AC, as that will also activate your muscles and push you away. While with DC, you’ll stick to it, as you grab onto it with a death grip. For advice on hurting yourself safely, just watch electroboom on yt.

  Every reply to your comment is correct. Together they explain everything wrong with the idea in that meme. I have no notes. Bravo @expatriado@lemmy.world @ZkhqrD5o@lemmy.world and @markz@suppo.fi .
