What Do the Colour-Coded Wires in USB Cables Practice?

Today, nearly of the hardware devices we connect to our CPUs are USB-driven, meaning that they require employ of a USB cord or cable. This includes your keyboard, mouse, webcam, memory flash drive, external hard drive, camera or digicam, video camera, possibly your speakers, and more. They all demand a USB cord to connect to your computer.

So, what is within the cord, exactly? USB stands for "universal serial bus," and there are four wires inside of it—usually red, green, white, and black. Each of these wires has a corresponding code or purpose.

USB Cable Colors and What They Mean

• The red wire is a positive power wire with v volts of DC power.
• The blackness wire is the ground wire (similar to most all electronic devices).
• The white wire is a "positive" data wire.
• The green wire is a "negative" data wire.

Culling Wire Colour Meanings for USB Cables

Some USB cords have different wire colour combinations, like orangish, blue, white, and dark-green. In this case:

• The orange wire is a positive ability wire with 5 volts of DC power.
• The white wire is a ground wire.
• The blueish wire is the "negative" data wire.
• The green wire is the "positive" data wire.

Hi, I'1000 trying to attach my phone charger to a battery made of pennies, and I got the battery to work (information technology fabricated 6.5 volts), but I don't know how to attach it to the charger. The charger has four wires (cerise, light-green, blackness, and white), only I don't know how to adhere them. Whatsoever ideas?

S P Walsh on Oct 24, 2018:

#Mark Mann: you make a few points of note but then make the same mistake y'all are trying to right: People's republic of china, as with any modern state does have standards for all these things but as far as I am aware, in their domestic market place the standards are often honoured more than in the breach than the observance.

The wire colours you have referred to, such as the green yellow for globe is really required by a multitude of international standards to be reserved for the purposes of protective earth conductors. For the most function, in that location are no specific colours associated with an active or neutral for example in a permanent installation mains circuit. Any associations of colour to purpose in mains wiring is purely conventional rather than specified by a standard. Mains cables on the other hand are far too uniform to be accidental.

The whole world is converging (and has been for over 20 years) to earth wide compatible standards which is why the U.s. is moving to 115/230 (and has been for a very long time) and here in Aus we are changing from 240 to 230 and parts of europe are changing from 220 to 230. Notice the 230 is the mutual theme. :-)

While American Wire Gauge is common place in many parts of the world and especially in certain industries (transformer manufacture for example) it is profoundly unpopular with engineers everywhere except perhaps the United states. Information technology is a totally useless wire specification for all but the wire manufacturers. Does it help yous to know that a wire has the diameter of a wire fatigued from 1oz of copper to 24ft in length? Or would you rather know the diameter or cross exclusive area?

And so I'm afraid where you lot say China likes yellow/dark-green for earth, it is actually the vast majority of the planet that demands yellow/green for earth and if you don't and then that makes you the odd human being out and it does non signify anything bad virtually China or any of Asia, Australasia, Europe, Due south America etc etc.

Your underspec'd wires are an artefact of the now crazy AWG standard which just does not have proper near equivalents to many mutual wire sizes spec'd in mm2. That problem as well has more to do with the US holding fast to AWG when the rest of the earth went metric decades ago.

Sad, but these are the facts about this, they are not evidence of a stupidity in the inhabitants of the rest of the planet.

Mark Isle of mann on July 29, 2018:

Please be careful with generalized comments every bit in the article, "Black has always been the ground wire in almost all electronic devices." Terms like "well-nigh" are too subjective" and this is a technical commodity right? Moreover, the statement is false! Red china the worlds largest producer of consumer electronics uses BLANK and Dark BROWN for the POSITIVE (Non-Ground) side for Air conditioning Circuits. I sympathise USB is 5V DC typically around .5A with Smart Phones Fast Charging with as much every bit 2A, all the same never the less, CHINA is taking over, at to the lowest degree by the numbers, and they do Not subscribe to our colors that were fabricated pop past the American Automotive Industry. Incidentally Red china likes Bluish for negative and YELLOW/Light-green for Earth Ground. China also does not follow the AWG. In CHINA wires are ALWAYS "under specification" when an AWG is called out. They will commonly misstate raw materials particularly "copper" and "Oxygen Gratis Copper." Economically, Simulated STATEMENTS from Prc "e'er" or let me say "Unequivocally" is in their Economic Favor (i.eastward. they benefit past the false statement in terms of universal value and commutation).

I have a low contour mini fuse (5V) plugged into a non-used 12V keyed on fuse slot that is reduced to 5.4V where I want to splice in the Garmin USB cablevision. The problem is the line conveying 5V has 2 wires Ruddy and BLACK (I presume are POS and NEG). The 2 wires to the USB plug are RED and GREEN ( I idea would be POS and NEG too). When I splice the Blackness to GREEN and Reddish to RED I get nix at the USB plug andd the Dash Cam does Not turn on. Any help would exist appreciated!
