what is black wire with white stripe？
The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. for the "wall wart" power supplies. Usually* the wire with the white stripe or the dashed lines carries the "positive" (+) end, while the other, unmarked wire carries the "negative" (-) end.2012年9月4日
Also asked,What does a black wire with a white stripe on it mean?
If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive.
Likewise,What is black wire with white stripe on ceiling fan?
Ceiling Fan Blue Wire Note: In some cases a black wire with a white stripe is used for the light fixture of the ceiling fan. If a second wall switch is not being used then the blue wire also connects to the black wire of the circuit power source.
In this regard,Is white wire with black stripe positive or negative?
For example, if you have a cable with a black-and-white-striped wire as well as a solid-color wire, connect the black-and-white-striped wire to the negative terminal at each end and the solid-color wire to the positive terminals.
Besides,Is the speaker wire with the stripe positive or negative?
When trying to identify speaker wires, you will have to look for two different colors on the wires. The silver wire is typically going to be the positive speaker wire, and the copper wire is the negative.
1:376:03How to identify positive and negative electrical wires - YouTubeYouTube推荐的剪辑从此处开始推荐的剪辑到此处结束When you're doing speakers amps things like that you have this is a typical speaker wire some largeMoreWhen you're doing speakers amps things like that you have this is a typical speaker wire some large or some smaller the silver is usually your negative and the copper is your positive side. And also
Negative - The wire for the negative current is black. Ground - The ground wire (if present) will be white or grey.
This means you need to be consistent when wiring the positive and negative sides of the speaker and amp. Most wires have a white line on the positive side and some have gold and silver wires to designate positive and negative. I use the white line or the gold side for positive and the other for negative.

One of the black and white wires goes to the light fixture. The other black and white wires are the electrical circuit for the switch. If the light can be turned on or off from switches at each side of the room, you'll see a blue wire that connects the electrical circuits for three-way switches.
In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means. In some cases, there will be small writing on the wiring case.
The Round / Smooth Side is Always Positive. If the wire is Black and hooked to AC, then the Wire is Positive and White is Negative. If the wires are Red and Black (for DC Purposes), then Red is Always Positive and Black is Always Negative.
