Mnemonics are used to help memorize the electronic color codes for resistors. Mnemonics describing specific and relatable scenarios are more memorable than abstract phrases.
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.
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 watts of electrical power as heat may be used as ...
Resistors (and other elements with resistance) oppose the flow of electric current; therefore, electrical energy is required to push current through the resistance. This electrical energy is dissipated, heating the resistor in the process. This is called Joule heating (after James Prescott Joule ), also called ohmic heating or resistive heating .
^ 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.

Originally meant also as part marking code, this shorthand notation is widely used in electrical engineering to denote the values of resistors and capacitors in circuit diagrams and in the production of electronic circuits (for example in bills of material and in silk screens ). This method avoids overlooking the decimal separator, which may not be rendered reliably on components or when ...
