  2. Electronic color code - Wikipedia

    en.wikipedia.org/wiki/Electronic_color_code

    Electronic color code. Appearance. A 2.26 kΩ, 1%-precision resistor with 5 color bands ( E96 series ), 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 ...

    ^ a b Before yellow and grey colored rings were assigned to tolerance values of ±0.02% and ±0.01% with IEC 60062:2016, some manufacturers used yellow and grey as substitute for gold (±5%) and silver (±10%) colored rings in high-voltage resistors to avoid metal particles in the lacquer.

  5. Alternating current - Wikipedia

    en.wikipedia.org/wiki/Alternating_current

    The voltage delivered to equipment such as lighting and motor loads is standardized, with an allowable range of voltage over which equipment is expected to operate. Standard power utilization voltages and percentage tolerance vary in the different mains power systems found in the world.

  6. RKM code - Wikipedia

    en.wikipedia.org/wiki/RKM_code

    The RKM code, [1] also referred to as "letter and numeral code for resistance and capacitance values and tolerances ", [1] "letter and digit code for resistance and capacitance values and tolerances", [2] [3] or informally as "R notation" [4] [5] [6] [7] [8] [9] is a notation to specify resistor and capacitor values defined in the international ...

  7. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography and colored lighting. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors .

  8. Resistor - Wikipedia

    en.wikipedia.org/wiki/Resistor

    Resistor. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

  9. E series of preferred numbers - Wikipedia

    en.wikipedia.org/wiki/E_series_of_preferred_numbers

    The E series is a system of preferred numbers (also called preferred values) derived for use in electronic components. It consists of the E3, E6, E12, E24, E48, E96 and E192 series, [1] where the number after the 'E' designates the quantity of logarithmic value "steps" per decade. Although it is theoretically possible to produce components of any value, in practice the need for inventory ...
