Fast identification of color ring resistance techniques

At present, domestic or imported TV sets, radio recorders widely used color ring resistance, its advantage is in the process of assembly, debugging and repair, no need to stir the components, can be in any Angle to see the color ring, read out the resistance, very convenient to use. In the past magazines have introduced the color ring resistance reading method, according to its reading method, to carry out conversion, more trouble, here is a rapid identification of resistance.

The first and second of the four color rings represent the first two digits of the resistance  respectively. The third ring represents the multiplier; The fourth ring represents error. The key to rapid recognition is to determine the resistance  in a certain order of magnitude according to the color of the third ring, such as when, or tens of K, and then "substitute" the number read out of the first two rings, so that the number can be read out quickly.
