Resistor values made easy.


The following chart is a
guide to help you easily select the right resistors for your project with
out having to scratch your head trying to remember the colours of the
resistors you need.

Violet Green 7R5 75R 750R 7K5 75K 750K 7M5 75M
Grey Red 8R2 82R 820R 8K2 82K 820K 8M2 82M
White Brown 9R1 91R 910R 9K1 91K 910K 9M1 91M

Example on how to use the
chart:



Say you want a 47K resistor,
find 47K in the chart, go to the left and find it's two colours (which
are yellow and violet), then go up from
47K to find the third colour (which is orange)


So that resistors colours
are: yellow violet orange


 


The next band
after those three colours indicates the resistor tolerance. which are
as follows.




Colour Fourth band
Brown 1%
Red 2%
Green 0.5%
Blue 0.25%
Violet 0.1%
Gold 5%
Silver 10%
None 20%


This guide
should work with all E12 and E24 resistors and maybe other types too.
