Do you wonder what the resistor color codes on your resistor mean?

Resistors have color bands on them. Usually 4 or 5. You can easily figure out the resistance value of your resistor by looking at theses bands and comparing them with the colors in the table below.

Further down this page, you’ll find examples of how to use the color table.

**Bookmark this page and print out the table below to quickly find the resistor color codes when you need them.**

## How To Use The Resistor Color Codes Table

In the resistor color codes table you have digits, a multiplier, and a tolerance.

The **multiplier** tells you what you need to multiply your **digits** with to get the value. The **tolerance** tells you how accurate this value is.

If your resistor has four color bands:

- The first two bands give you the digits
- The third band gives you the multiplier
- The fourth band gives you the tolerance

If your resistor has five bands, **the first three bands** give you the digits. And the following to give you the multiplier and the tolerance.

### Example #1

This resistor has four bands. The resistor color codes are *yellow – purple – orange – gold*.

From the table above we find that this means:

- Digit
**4** - Digit
**7** - Multiplier
**1000** - Tolerance
**5%**

47 multiplied with 1000 is 47000.

So this is a resistor with 47000 Ohms (47k Ohms).

Tolerance 5% means that the real value could be 5% higher or lower than 47k.

### Example #2

This resistor has five bands. The resistor color codes are *orange – green – black – red – brown*.

From the table above we find that this means:

- Digit:
**3** - Digit:
**5** - Digit:
**0** - Multiplier:
**100** - Tolerance:
**1%**

350 multiplied with 100 is 35000.

So this is a resistor with 35000 Ohms (35k Ohms).

Tolerance 1% means that the real value could be 1% higher or lower than 35k.

I’m glad you like it!

Your exlanation of 4 band & 5 band colour code using single colour-chart is excellent; and needs no further comparision between two types of resistorcolour code.

Great to hear!

This is far better than what we learn at school!!!

Mr Nchabeleng says

From which side of the resistor do we start checking the sequence of the colours?

admin says

Good question.

Make sure you have the tolerance band on the right when looking at your resistor.

Often you’ll see that the last band, the tolerance band, is a bit further away from the rest of the bands. If not, then look for a band that is silver or gold, only the tolerance band can be silver or gold.

Best,

Hey Ram,

If you get a message that the transaction was unsuccessful or declined, you need to talk with your bank. It might be that they have restrictions on international payments.

If the Tolerance is lets say 5%, as you said that it could be greater than or less then 45k. How do we know if it is greater or lesser? Or does it not matter much that it might do more or less then what it color bands say it has?
