Resistor color code 4 band
When you look at the tolerance usually it’s a 5% a gold band, you can expect that the actual resistance of the resistor will be somewhere between 5% higher or lower than the rated value. The tolerance is the amount that the resistance can be over or under its rated value, the amount to expect actually. First, we are going to start with the tolerance band. Let’s take a look at another resistor 1K ohm. The same method applies to all the resistor types. So, using the resistor color codes, we read a resistor from left to right while keeping the tolerance band on the right side. You will need to keep the tolerance band on the right side. Just connect the test leads of the multimeter with the two leads of the resistor, set the selection knob of the multimeter on the resistance and that’s it.īut, if you read a resistor using the color bands. You don’t have to be worried about the tolerance band. If you are using a Multimeter to find the resistance of a resistor, then it doesn’t matter which probe of the Digital Multimeter is connected with which lead of the resistor. Before, we dig deeper, there are a few things that you should know.
Resistor color code 4 band how to#
With the help of this diagram, I will try to make it easier for you to understand, how to find the resistance of a resistor by only looking at the color bands. It helps you sort out unknown resistors a lot quicker and stuff like that. If the values are not printed then of course you can also use the multimeter to get the resistance values, but it is still a great idea to get familiar with the resistor color codes. On some strips they hand wrote the values, these resistors are 220-ohm. They come on these paper strips with the resistance value printed, as you can see in the image given above 150-ohm resistors. Other resistors have it on this little strip. This resistor package has the resistance value printed on the package itself 470-ohm. Now, of course, resistors also come in packaging. When you get more advanced into electronics, a different type of resistor might make a difference, but for the beginning what you’re mainly worried about is the amount of resistance that the resistor has and this is indicated by the color codes. Now, we’re just going to worry about the resistor color codes. The metal film resistor happens to be a lot more accurate, but anyhow, we’re not going to worry about this.
Here is an image of two resistors, they’re made of a different material but they’re both resistors, for the most part, they work exactly the same. You can remember the colors order by remembering the following line. You will be able to read a resistor with a single glance, of course, if you remember the resistor color chart. If you know the method of reading a 4 band resistor or 5 band resistors then you won’t need a multimeter. Resistor Color Codes- One of the first things, you want to try to understand to get familiar with, when you’re learning electronics is the resistor color codes.
