2. 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.

3. List of electronic color code mnemonics - Wikipedia

   Color coded resistors Mnemonics are used to help memorize the electronic color codes for resistors . Mnemonics describing specific and relatable scenarios are more memorable than abstract phrases.

4. Resistor - Wikipedia

   en.wikipedia.org/wiki/Resistor

   Various resistor types of different shapes and sizes. 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.

5. 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 ...

6. E series of preferred numbers - Wikipedia

   en.wikipedia.org/wiki/E_series_of_preferred_numbers

   Two decades of E12 values, which would give resistor values of 1 Ω to 82 Ω. 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 ...

7. List of resistors - Wikipedia

   en.wikipedia.org/wiki/List_of_resistors

   Old style "dog bone" resistors with "body, tip, dot" color code marking Three carbon composition resistors in a 1960s valve (vacuum tube) radio Carbon composition resistors (CCR) consist of a solid cylindrical resistive element with embedded wire leads or metal end caps to which the lead wires are attached.

8. Electronic symbol - Wikipedia

   en.wikipedia.org/wiki/Electronic_symbol

   Electronic symbol. An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country ...

9. Electrical resistance and conductance - Wikipedia

   en.wikipedia.org/wiki/Electrical_resistance_and...

   The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction. The SI unit of electrical resistance is the ohm (Ω ...
