Electronic Components

Resistors

Resistor Color Rings

A Resistor Value is determined

by its color band and is measured in ohms

First Ring is units

Second Ring is Ten

Third Ring is number of zero’s

Fourth Ring is tolerance

Resistor Color Code Values

First Ring

Black = 0

Brown = 1

Red = 2

Orange = 3

Yellow = 4

Green = 5

Blue = 6

Violet = 7

Gray = 8

White = 9

Second Ring

Black = 0

Brown = 1

Red = 2

Orange = 3

Yellow = 4

Green = 5

Blue = 6

Violet = 7

Gray = 8

White = 9

Third Ring Multiplier

Silver = X .01

Gold = X .1

Black = X 1

Brown = X 10

Red = 2 = X 100

Orange = 3 = X 1000

Yellow = 4 = X 10,000

Green = 5 = X 100,000

Blue = 6 = X 1000,000

Violet = 7 = X 10,000,000
