Resistor-Code

A resistor code is identified by its pattern of color of bands. There are3, 4, 5 and 6 band resistors. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator.

Examples
3 bands:
Yellow, violet, black --> 47 ohm 20%
Orange, orange, brown --> 330 ohm 20%
Brown, black, red --> 1k 20%

4 bands:
Green, blue, red, gold --> 5.6kohm 5%
Red, yellow, orange, gold --> 24kohm 5%
Blue, gray, yellow, silver --> 680k 10%

5 bands:
Red, yellow, orange, black, brown --> 243 ohms, 1% precision 5-band resistor
Yellow, violet, gold, gold, yellow --> 4.7 ohms, 5% - this resistor is calculated with the 4-band rule (the yellow band is ignored).
Orange, black, black, brown, brown --> 3.00 k ohms, 1% - note: this is a non-standard 1% (E96) resistor, but some manufacturers make

6 bands:
Red, red, brown, brown, brown, red --> 2.21k, 1% 50ppm/°C
White, black, white, brown, red, red --> 9.09k, 2% 50ppm/°C
