    en.wikipedia.org/wiki/Electronic_color_code

    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.

    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.

    4 Cu(O 2 CCH 3) 2 + N 2 H 4 + 2 H 2 O→ 2 Cu 2 O + 8 CH 3 CO 2 H + N 2. Aqueous cuprous chloride solutions react with base to give the same material. In all cases, the color of the cuprous oxide is highly sensitive to the procedural details. Cu 2 O degrades to copper(II) oxide in moist air.

  8. 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).

  9. Cooper pair - Wikipedia

    en.wikipedia.org/wiki/Cooper_pair

    This distance is usually greater than the average interelectron distance so that many Cooper pairs can occupy the same space. [5] Electrons have spin-12, so they are fermions, but the total spin of a Cooper pair is integer (0 or 1) so it is a composite boson. This means the wave functions are symmetric under particle interchange. Therefore ...
