The commonly used resistors in breadboard circuiting are carbon film
resistors and metal film resistors. Manufacturers use a color code system
that consists of bands of color painted on the resistor and make it easier to
identify the resistor value. There are typically four bands or five bands on a
resistor, and each band represents a specific digit in the resistance value as
labeled in the illustration.
For 4-band or 5-band resistors, each band represents a specific digit in
the resistance value. For color banded resistors, the first two or three color
bands represent the significant digits, and the last band represents the
multiplier, which indicates the number of zeros to add to the significant
digits.
