Resistor colour codes

first 3 bands on left are the values, 3rd is the multiplier, the right hand band is the tolerance.

so in the above we have 1, 0, 0, 3

this is 100 with 0x3 = 100,000 = 100k Ohms resistor.

(sometimes the 3rd band is omitted)

 

Black = 0

Brown = 1

Red = 2

Orange = 3

Yellow = 4

Green = 5

Blue = 6

Violet = 7

Grey = 8

White = 9

 

Tolerance bands

silver = +/- 10%

gold = +/- 5%
