People who are engaged in electrical maintenance, often encounter color ring resistance, as long as you know the calculation rules of color ring resistance, the size of the resistance is easy to calculate, if you don't remember the number represented by the color ring, it is also very convenient to calculate the color ring resistance with a WeChat applet.
However, there are two problems that are difficult to determine when calculating the resistance of the color ring. First, it is difficult to distinguish what kind of color, especially brown, orange, and gold may be difficult to distinguish due to the use of time.
The second is that I don't know where to start, which originally required a larger spacing between the magnification and the error color wheel, but in fact it is difficult to distinguish.
I don't understand why the rules don't change the error color circle to a dotted line, isn't it easier to use!
