3. 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.

4. Resistor - Wikipedia

   en.wikipedia.org/wiki/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. High-power resistors that can dissipate many ...

   The 10k resistor is used as a pull-up resistor, which keeps the terminal high (+5 volts) until it's pulled low by the switch, and the resistor itself keeps the ground from having a direct path ...

6. RKM code - Wikipedia

   en.wikipedia.org/wiki/RKM_code

   The RKM code, also referred to as "letter and numeral code for resistance and capacitance values and tolerances", "letter and digit code for resistance and capacitance values and tolerances", or informally as "R notation" is a notation to specify resistor and capacitor values defined in the international standard IEC 60062 (formerly IEC 62) since 1952.

7. Johnson–Nyquist noise - Wikipedia

   en.wikipedia.org/wiki/Johnson–Nyquist_noise

   Johnson 's 1927 experiment showed that if thermal noise from a resistance of with temperature is bandlimited to bandwidth , then its root mean squared voltage is in general, where is the Boltzmann constant. Johnson–Nyquist noise ( thermal noise, Johnson noise, or Nyquist noise) is the electronic noise generated by the thermal agitation of the ...
