"Red, black and gold" is 220 euros 10%, and "brown, black, gold and gold" is wrong. Gold rings and silver rings do not mean that numbers can only represent mistakes, and there will not be two gold rings at the same time.

In addition, the gold and silver circles must be read behind the resistance color circle. For example, "brown, black and gold" is the correct order, while "gold, black and brown" is definitely wrong.
