copper is positive
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,
Generally, yes.
Negative * positive = negative Positive * positive = positive Negative * negative = positive
The red wire is Positive, (+) and the Black wire is Negative. (-)
The positive speaker wire is red while the negative speaker wire is black on a 2008 pathfinder.
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
Red is positive, Black is the negative
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
The left rear speaker wire positive is -Yellow/Blue negative is - Black/Blue The right rear speaker wire positive is - Yellow/Red negative is - Gray/Red
Black for negative and red for positive.
Red to positive, black to negative
Positive is normally red or white with a red stripe. Negative is usually green or on rare occasions black. A multimeter will verify this.
In DC measurements, the red wire typically indicates the positive polarity (+) while the black wire indicates the negative polarity (-). It's important to connect the red wire to the positive terminal and the black wire to the negative terminal when taking measurements to ensure accuracy and avoid damaging the equipment.
The positive wire for the 2005 Toyota Tacoma tail light is red with white stripes. The negative wire is white with black stripes.
In a DC circuit Red is positive and Black is negative. In AC systems White is neutral and Ground is green or green-yellow stripe.
