  2. List of electronic color code mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_electronic_color...

    The first letter of the color code is matched by order of increasing magnitude. The electronic color codes, in order, are: 0 = Black; 1 = Brown; 2 = Red; 3 = Orange; 4 = Yellow; 5 = Green; 6 = Blue; 7 = Violet; 8 = Gray; 9 = White; Easy to remember. A mnemonic which includes color name(s) generally reduces the chances of confusing black and brown.

  3. 25-pair color code - Wikipedia

    en.wikipedia.org/wiki/25-pair_color_code

    A common application of the 25-pair color code is the cabling for the Registered Jack interface RJ21, which uses a female 50-pin miniature ribbon connector, as shown in the following table. The geometry of the pins of the receptacle (right hand image) corresponds to the pin numbers of the table.

    A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.

  5. AC power plugs and sockets - Wikipedia

    The type 11 plug is unearthed, with two 4 mm diameter round pins spaced 19 mm apart. The type 12 plug adds a central 4 mm diameter round earth pin, offset by 5 mm. The type 12 socket has no recess, while the type 13 socket is recessed. Both sockets will accept type 11 and type 12 plugs, and also the 2.5 A Europlug.

    The USB 2.0 specification requires that cable delay be less than 5.2 ns/m (1.6 ns/ft, 192 000 km/s), which is close to the maximum achievable transmission speed for standard copper wire. The USB 3.0 standard does not directly specify a maximum cable length, requiring only that all cables meet an electrical specification: for copper cabling with ...

    en.wikipedia.org/wiki/G-type_main-sequence_star

    A G-type main-sequence star (spectral type: G-V), also often, and imprecisely, called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about 5,300 and 6,000 K (5,030 and 5,730 °C; 9,080 and 10,340 °F ).

  8. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    A diagram demonstrating additive color with RGB. The RGB color model is an additive color model [1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

  9. Color code - Wikipedia

    en.wikipedia.org/wiki/Color_code

    25-pair color code chart used in certain kinds of wiring. A color code is a system for encoding and representing non-color information with colors to facilitate communication. This information tends to be categorical (representing unordered/qualitative categories) though may also be sequential (representing an ordered/quantitative variable).
