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 marked ...

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 ...

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 ...
