Resistor Color Codes – 4,5 and 6 Band – Electronics

Who needs to identify the value of an electrical resistance based on the marked color code but does not have a measuring device, I’ve attached some very suggestive pictures below that can help you calculate the electrical resistance (Ohm) simply and quickly.

Most resistors have coded the value of resistance in 4 or 5 colors, but there are also variants in 6 colors, the essential are only the first 4 bands, where the last band (4) is the multiplication factor.

For those with 6 bands: the band 5 is tolerance and last one is the temperature coefficient, the rest are explained above!
