20 resistors have only 3 color bands - the tolerance band is missing.
#20 ohm resistor color code code#
If there is no tolerance band, then find the side that has a band closest to a lead and make that the first band. Tolerance Brown + 1 + 2 Red + Gold 5 + Silver - 10 + None - 20 Resistor Color Code 4 Band 30 ohm. A color is assigned to each tolerance: gold is 5, silver is 10. The resistor value is read from the left to right.

Generally, the tolerance for the three-band resistor is ☒0 which means no tolerance strip. In a three-band resistor color code, the first two bands denote the resistance values and the third band is a 1-multiplier band. The Gold or Silver band is always placed to the right. The resistor with 3 band color code is shown below.
