In the color code chart, you’ll determine that green stands for 5 and blue for 6. In the below figure, the 4 bands are green, blue, red, and gold. The four-band color code is the most common variation, having two bands for resistance value, one multiplier, and one tolerance band.

The chart below shows how to determine the resistance and tolerance for resistors.

The resistance should be measured with an ohmmeter, if not sure.

Checking the manufacturer’s documentation is also essential to be sure about the color-coding system used.

The first band is usually the closest to a lead, a gold or silver band is always the last band and it indicates tolerance.

Sometimes the increased space between bands 3 and 4 provides an indication of the reading direction. The reading direction is not always clear.Below are tips to know when reading the codes of resistors: Resistor color codes are color bands or numerical codes wrapped around resistors so that their properties such as power rating, value, tolerance, and reliability of a resistor. 6.4.1 Watch the video below to learn more about the color code of resistors:.6.3 5 band resistors with silver or gold 4th band:.6.2 Single black band or zero-ohm resistor:.
