How to Read the Resistor Color Code?

Posted on

Resistor Color Code – Previously we have studied about Resistor. But how do we know the resistance value of the resistor? Well, to be able to find out the value of a resistor’s resistance there are two ways friends. First based on the color bracelet and the second is printed directly on the resistor body. In this tutorial I will explain how to read the color bracelet on a resistor. The most basic thing to know the color value of a resistor is to remember the color table. Consider the following resistor color table.

How to read Resistor Value

You must remember the color code above. The priority to remember is the Color and Numbers table because it represents the excavation column. Look at the excavation column, the term multiplication can be replaced with “Number of Zero”. Look at again in brown column, the value is 1. Brown is worth 1, which means that in a bracelet or column multiplied by the value 10 or the number 0 is one. Red has a value of 2, zero is two and so on and this only applies in the multiplier. If you are still confused, here I will give two examples of how to read the color bracelet on the resistor to find out what the resistor resistance value is.

1. First example

How to Read the Resistor Color Code

In Above image there is a resistor that I provide. This resistor has 4 color bands on the body of the resistor. Please  attention to the color table again to see the value of the color of the bracelet. The way to read is:

Brown, Black, Orange and Gold.
1, 0 x 1,000 and ± 5%.
Result: 10,000 Ohm ± 5%
(read: 10.000 or 10K Ohm with tolerance of ± 5%);

2. Second Example

How to Read the Resistor Color Code

The way to read is:

Orange, Orange, Red and Gold.
3, 3 x 100 and ± 5%.
Result: 3,300 Ohm ± 5%
(read: 3.300 or 3K3 Ohm with tolerance of ± 5%);

How to Read the SMD Resistor Value

To read the SMD resistor it is easier compared with a resistor that has a color bracelet. Below are examples of SMD resistors. Generally SMD resistors have the values ​​listed on their bodies. Look at the following picture:

1. First example
