Fast identification method for color ring resistance 1

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.diode

Accurately remembering the resistance range represented by the color of the third ring is the key to quick recognition. Specifically, it is:

Gold: What is the temperature and Ω

Black: Several tens of ohms

Brown: several hundred or tens of ohms

Red: What time is k Ω

Orange: several tens of k Ω

Yellow: several hundred or tens of k Ω

Green: What time is M Ω

Blue: Several tens of M Ω

In terms of magnitude, they can be divided into three major levels on the body, namely: gold, black, and brown are Ohmic level; Red, orange, and yellow are in the thousand euro range; Green and blue are in the megaohm range. This division is for the convenience of memory.diode
