How to identify color ring resistors 1

At present, color ring resistors are widely used in domestic or imported televisions and recorders. Their advantage is that during assembly, debugging, and repair processes, the color ring can be seen at any angle without the need to toggle the components, and the resistance value can be read out. They are very convenient to use. In the past, magazines have introduced the color ring resistance reading method. When reading according to this method, conversion is required, which is more complicated. Here, we introduce a fast method for identifying resistance values.diode

The first and second rings with four color rings represent the first two digits of the resistance value, respectively; The third ring represents magnification; The fourth ring represents error. The key to quick identification is to determine the resistance value within a certain range of orders of magnitude based on the color of the third ring, such as the point, K, or tens of K, and then enter the generations read from the first two rings, so that the numbers can be quickly read.diode

Here are several key points to master this method:

(1) Memorize the numbers represented by each color in the first and second rings. You can remember it as follows: Brown 1, Red 2, Orange 3, Yellow 4, Green 5, Blue 6, Purple 7, Gray 8, White 9, Black 0. Read it together like this and repeat it a few times to remember. Accurately remembering the resistance range represented by the color of the third ring is the key to quick recognition. Specifically, it is:diode
