This post is going to be another short one that covers some basics but may also be a good review for electronics veterans alike.
The topic is resistor color code.
If you’re just starting in electronics you don’t want to miss this one as it will discuss one of the most basic yet important things you need to know.
Now, I know some of you may be thinking something like “…yeah, but there are resistor color code calculators online so why bother?”
Right, there are some helpful resistor color code calculators out there that can help you when you’re learning. Use these to check yourself in the beginning.
But it would be a lot more efficient and quicker if you could know the value of a resistor within a second or two just by looking at it.
Oddly enough, none of the courses I had to take to get my degree in electrical engineering talked about this. Nor do I recall any of the texts mentioning it.
Previous to college and my EE degree, I earned a diploma in electronics, computers, and robotic technology at a for-profit tech school. This took me one year.
There, resistor color code was one of the first things we learned.
By the way, if you want to know more about resistors, here is a post about resistor types and their differences.
Now on to color code…
