0• Wire-wound resistors have a label indicating resistance and power ratings.
• A majority of resistors have color bars to indicate their resistance magnitude.
• There are usually 4 to 6 bands of color on a resistor. As shown in the figure below, the right most color bar indicates the resistor reliability, however, some resistor use this bar to indicate the tolerance. The color bar immediately left to the tolerance bar (C), indicates the multipliers (in tens). To the left of the multiplier bar are the digits, starting from the last digit to the first digit.
