  2. 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.

  4. Electronic color code - Wikipedia

    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.

  5. 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).

  6. Tip and ring - Wikipedia

    en.wikipedia.org/wiki/Tip_and_ring

    Tip and ring. 1: Sleeve, 2: Ring, 3: Tip, 4: Insulators. Tip and ring are the two conductors or sides of a telephone line. Their names are derived from the telephone plugs used for connecting telephone calls in manual switchboards. One side of the line is connected to the metal tip of the plug, and the second is connected to a metal ring behind ...

  7. Twisted pair - Wikipedia

    en.wikipedia.org/wiki/Twisted_pair

    A twisted pair can be used as a balanced line, which as part of a balanced circuit can greatly reduce the effect of noise currents induced on the line by coupling of electric or magnetic fields. The idea is that the currents induced in each of the two wires are very nearly equal. The twisting ensures that the two wires are on average the same ...

  8. Anderson Powerpole - Wikipedia

    en.wikipedia.org/wiki/Anderson_Powerpole

    Anderson Powerpole. The Anderson Powerpole is a family of electrical connectors by Anderson Power Products (APP), [ 1] although plug compatible connectors are now available from alternate sources. Specific variants of this series of connectors have become de facto standards for conveying "higher power" direct current (DC) electrical power ...

  9. Singlet state - Wikipedia

    en.wikipedia.org/wiki/Singlet_state

    In quantum mechanics, a singlet state usually refers to a system in which all electrons are paired. The term 'singlet' originally meant a linked set of particles whose net angular momentum is zero, that is, whose overall spin quantum number . As a result, there is only one spectral line of a singlet state. In contrast, a doublet state contains ...
