Why does a battery snap have a red wire and a black wire?
Red wire=positive Black wire=negative
Which is positive and which is negative out of red wire blue wire white wire and black wire which go to positive?
When working with DC (direct current) voltage, IN GENERAL, red is positive and black is negative. But the reality is, a manufacturer may select different colored wires to represent different things, and it is entirely up to the manufacturer to make those decisions.But since this question is under the heading, "Home electricity", you may have asked the wrong question, since home wiring is AC (alternating current), and there is no such thing as a positive or negative wire.
