Positive wire is red, at least on automobile batteries.

Hot is positive.
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
yes.. had to find out myself with a multimeter and phone test,, white wire is positive on a samsung travel adapter.
Commonly the red should be positive but not always. Use a volt meter to find out for sure. Really need more information as to what this wire is for and where it is located to give a good answer.
Red to positive, black to negative
positive wire to another positive wire
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.
The red wire is Positive, (+) and the Black wire is Negative. (-)
copper is positive
The positive wire on most batteries is red. If both are black, look for the positive sign by the electrode.
The copper wire is typically positive. However, the best way to determine which is positive and negative is by referring to the user manual or guide that came with the speakers. The writing on the silver wire is likely there to indicate which wire is positive.
The red wire typically indicates positive polarity, while the black wire indicates negative polarity. This color coding helps ensure correct connections are made when connecting the battery snap to a device or circuit, minimizing the risk of short circuits or reverse polarity.
The negative wire is grounded.AnswerThe negative wire is grounded.
The positive speaker wire is red while the negative speaker wire is black on a 2008 pathfinder.
Hot is positive.
