Some people look at a venerable resource like resistor color code charts and see something tried and true, but to [Andrew Jeddeloh], there’s room for improvement. A search for a more intuitiv… ...

A search for a more intuitive way is what led to his alternate cheat sheet for resistor color codes. Color code references typically have a reader think of a 560 kΩ resistor as 56 * 10 kΩ, but ...

If our example resistor ended in gold (orange, white, black, gold), its 39 Ohms value could be five percent higher or lower. For a possible minimum of 37.05 or a maximum of 40.95.

Resistor color code human interest story. I once worked with an engineer that often checked his resistors with a multimeter before use. I just assumed that he was just being careful (certainly more ...
