The fun of having a giant resistor-shaped Ohmmeter is that it reads back the resistance by displaying the color code. If you’re not too hot with decoding those bands there’s a helper band to the right ...

The values or ratings of electronic components are indicated by the electronic color code that was developed in the early 1920s. It is not only seen in resistors, but also in capacitors, inductors, ...

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 careful than I…). Then one day, he asked me ...

Today is the 2 nd of February in the year 2022, and red is the color used to encode two. Unfortunately, today’s five-band scheme uses a different color for the five band that indicates the tolerance ...

Hacker/maker/educator Jimmie Rodgers has a new tattoo. What do you see? Some pretty boxes? Yes, it's that — but also so much more. Let us take you on a tour of its symbolic wonders. First, it's a ...

Here’s a tip from a wizened engineer I’ve heard several times. If you’re poking around a circuit that has failed, look at the resistor color codes. Sometimes, if a resistor overheats, the color code ...
