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 ...
If there’s one thing that will surely blind us, its reading resistor color bands. It doesn’t help that red looks exactly like orange, brown and black are indistinguishable, and different component ...
The Adafruit blog just posted a neat papercraft resistor calculator. If you haven’t yet learned the horribly offensive mnemonic for resistor color codes, now’s your chance to have a cheap and portable ...
