      Please do. I don’t know what’s wrong with it

      Edit: thanks folks! I feel like an idiot because that’s super obvious. :-)

        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.

            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 cables, 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,.

        If you connect one pole of the battery, it does nothing. If you connect both, it just shorts the battery via a path that doesn’t involve the downstairs neighbor.

        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.

      Maybe if you just connect one side of the life wire to it. And ground the other one. That could work better
