The wire leading to the bulb socket is the positive (+) wire. The vehicle body and frame acts as the negative (-) part of the circuit.The wire colour codefor positive is the green black one
Red wire=positive Black wire=negative
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.
yes
Red is positive while Black is negative.
It is traditional to use the copper colored wire as the positive. Of course, the electrons don't care what color the wire is as long as you hook it up the same at both ends!
positive wire to another positive wire
Positive wire is red, at least on automobile batteries.
The positive speaker wire is a solid color, your negative wire should have a stripe on it.

You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire! The positive wire has a potential difference of +110 V with respect to the negative wire.
copper is positive
The red wire is Positive, (+) and the Black wire is Negative. (-)
The positive wire on most batteries is red. If both are black, look for the positive sign by the electrode.
Red wire=positive Black wire=negative
Hot is positive.
