One of the first things you learn in electronics is how to identify a resistor’s value. Through-hole resistors have color codes, and that’s generally where beginners begin. But why are they ...

This is part of Electronic Design's 70th Anniversary series. Color coding is a common way to provide easy identification of characteristics like the resistance value of a resistor. Electronic ...

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 ...
