That is very different from "positive and negative" in a battery, which is direct current (DC): the two poles of the battery have different potential, with a (more or less) constant potental difference (voltage) of, for example, 1.2V; one pole is the "positive" one, the other the "negative". It connects to the neutral wire the white wire that links to the silver screw. electronics.stackexchange.com/a/33969/5163, How Intuit democratizes AI development across teams through reusability.
