The Gold or Silver band is always placed to the right. The resistor value is read from the left to right. If there is no tolerance band, then find the side that has a band closest to a lead and make that the first band.

Resistor Color Code Chart. Resistors are devices that limit current flow and provide a voltage drop in electrical circuits. Because carbon resistors are physically small, they are color-coded to identify their resistance value in ohms.
Resistor Color Codes. Most common resistors have four colored bands. The band at one end of the resistor will be a metallic color (gold, silver, or bronze). This indicates the accuracy of the resistor (+/- 5%, 10%, or 20%, respectively).
There are lots of different ways to mark the values on components. Most resistors use the color code and are fairly straightforward, but there are some exceptions. The most common are resistors marked RN55153J, or something similar. The ‘RN’ part of the number is fixed, the next two digits (55 in this example) indicate the power rating, the
To discern the specific values for a circuit, the resistors are marked with color coded bands that have a different number per color, as well as the tolerance of the resistor. Determine the values of all your resistors with this resistor color chart.
