Red wire is positive (+) and black wire is negative (-).
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
Red wire=positive Black wire=negative
The red wire is Positive, (+) and the Black wire is Negative. (-)
On an AC circuit for electric heating where no neutral wire is used, red jacketed red and black 2 wire is used. On a DC circuit red and black wires are used to differentiate between the positive and negative polarities.
The red wire goes to the positive (+), and the black wire goes to the negative (-).
The black wire means negative and the red wire means positive if that's what you where asking
The positive wire on most batteries is red. If both are black, look for the positive sign by the electrode.
YesCaveatIn general, when working with DC, the red wire is positive and the black wire is negative. In the US and Canada, when working with AC, the colored wires (red, black...) are "hot", the white wire is neutral and the green or bare wire is ground.Note that the above is NOT a requirement for "switch legs".
Black for negative and red for positive.
Red to positive, black to negative
Positive is usually the red wire. As we are discussing a battery, I assume that we are referring to DC. Red is the wire for Positive, Black would be Negative. The Black wire attaches to a ground point on most DC circuits. Had we been referring to an AC circuit, Black would be the 'hot' wire, white would be what is known as 'neutral' & green would be the Ground wire.
The 4-wire cable should have black, red, white and a green or bare wire. The 220 volts is between red and black. The white is neutral or common and there would be 110 volts between white and red and between white and black. The green or bare wire is the ground.
The positive speaker wire is red while the negative speaker wire is black on a 2008 pathfinder.
In a DC circuit, such as a car, the RED wire is usually the positive (hot) and the black wire is the negative (ground) In an AC circuit, such as your house, in the US both black and red are "hot" wires, with white being neutral.
Red is positive, Black is the negative
Red is positive black is ground.
The red battery wire goes on the positive + battery terminal no matter which side it is on. The black wire goes on the negative - terminal.
The red wire is the positive wire. The black wire is the ground wire. The white wire is the auxiliary wire.
The red wire is the positive wire. The black wire is the ground wire. The yellow wire is the speaker wire. The white wire is the auxiliary wire.

The ground wire is a black. The positive wire is red. The speaker wires are yellow and green. The auxiliary wire is white.
Positive is normally red or white with a red stripe. Negative is usually green or on rare occasions black. A multimeter will verify this.
The red wire is the positive wire. The black wire is the ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
The presence of the red wire has no any other importance. The red wire connecting to the speaker is attached to the positive terminal. The black wire connects to the negative terminal.
