How to Read the Color Code of a Resistor?

The resistor color code is read from left to right, with the first two or three rings representing the significant digits, followed by the multiplier ring, and finally the tolerance ring. 6-ring resistors also include the temperature coefficient ring.

What types of resistors does the Resistor Color Code Calculator support?

This calculator supports the color code calculation of 4-ring, 5-ring, and 6-ring resistors, covering all common resistor types on the market.

How to Use the Color Code Table?

1. Identify the Number of Rings

First, confirm whether the resistor is 4, 5, or 6 rings. The reading method varies slightly for different types of resistors.

2. Determine the Reading Direction

Usually, read from the opposite direction of the gold or silver ring. If there is no gold/silver ring, start reading from the side with the largest gap.

3. Calculate the Resistance

The first 2-3 digits are the significant digits, the multiplier ring determines the final value, and the tolerance ring indicates the accuracy range.
