Electronic ComponentsResistors

A Resistor Value is determined by its color band and is measured in ohms

First Ring is unitsSecond Ring is TenThird Ring is number of zero’sFourth Ring is tolerance

First RingBlack = 0Brown = 1Red = 2Orange = 3Yellow = 4Green = 5Blue = 6Violet = 7Gray = 8White = 9

Third Ring MultiplierSilver = X .01Gold = X .1Black = X 1Brown = X 10Red = 2 = X 100Orange = 3 = X 1000Yellow = 4 = X 10,000Green = 5 = X 100,000Blue = 6 = X 1000,000Violet = 7 = X 10,000,000
