5 band resistor color code code#
The first band you start with when reading resistor color code will be closer to one end of the resistor. Resistor manufacturers adopted this color code.
Now on to color code… Intro to Resistor Color CodeĪs the electronics industry evolved, one of the first things that the industry’s players did was standardize the color code marking on resistors.
There, resistor color code was one of the first things we learned.īy the way, if you want to know more about resistors, here is a post about resistor types and their differences. Previous to college and my EE degree, I earned a diploma in electronics, computers, and robotic technology at a for-profit tech school. Nor do I recall any of the texts mentioning it. Oddly enough, none of the courses I had to take to get my degree in electrical engineering talked about this. Use these to check yourself in the beginning.īut 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. Right, there are some helpful resistor color code calculators out there that can help you when you’re learning. Now, I know some of you may be thinking something like “…yeah, but there are resistor color code calculators online so why bother?” 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. If you know the answer i would like you to email me so that I can share with other fellow electronic repairer through this info repairing newsletter.This post is going to be another short one that covers some basics but may also be a good review for electronics veterans alike. However, from forum someone said that it is for the military purposes. As to why the resistor manufacturers add this ‘extra’ white band i really do not know. Just ignore the white color and proceed to calculate using the four color band formula. Actually it is a four color band resistor. The colors are orange, orange, red, gold, white. I will reveal the calculation about this unique five color band resistor. In fact i have already seen quite a number of them. There was a interesting five color band resistor which was very unique. In other words the use of five color band resistor is to make a circuit more precise and output the desire result as what the engineers want it to be. If that particular multimeter was designed using four color band resistor the result that it gets may be 8.5v, 9.5v or even 10 volt. For instance, if you measure a 9v battery the needle will point to may be 8.9v, 9v, or 9.1 volt. Why? Because the reading that you get whenever you measure current, voltage or ohm, the panel will show the nearest value. Most of the resistors circuit inside the multimeter are using five color band. If you open up an analog multimeter you will understand what I mean.
5 band resistor color code how to#
You may go to Google search engine and type resistor color code, resistor color coding, resistor color code calculator, or resistor color code chart to know more about how to calculate a five band resistor values. If with the five color band you will be able to calculate it (red, red, blue, red, brown) the last color which is brown represent 1% tolerance. The most you can get is 22k (red, red, orange and gold). For example in order to get the value of 22.6kohm, with four colors band resistor you will not be able to find it. The purpose of using the five color band resistor in a circuit is that it will provide a more accurate value compare to the four color band. In electronic repair, most of the time I came across five band resistor color code.
