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
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.
