Resistor Reference - Getting Started with Intel Galileo - page 154

For example, a resistor with the colors brown (1), black (0), orange (1K), and
gold (5%), as pictured in Figure C-1 , would have the value 10K (10,000) ohms
with 5% tolerance.

Figure C-1. This resistor has the color bands brown, black, orange, and
gold. This indicates that it's a 10K resistor with a 5% tolerance.

Band First Band Second Band Third Band (Multiplier) Fourth Band (Tolerance)

Color Brown Black Orange Gold

Value 1 0 x1K 5%

If you encounter a resistor with five color bands, it simply means that there's
an extra digit before the multiplier. See Table C-3 to determine the value.
