The Resistor Colour Code system is all well and good but we need to understand how to apply it in order to get the correct value of the resistor. The Standard Resistor Colour Code Chart : Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Select the number of bands, then their colors to determine the value and tolerance of the resistors or view all resistors Digi-Key has to offer. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. This tool is used to decode information for color banded axial lead resistors. 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. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
