B. Resistors Color Codes
The values of most of the resistors in your lab kit are indicated by color bands. These
color bands are painted on the body of each resistor and are decoded in the following manner:
Look at the resistor. There will be a group of color bands clumped together at one end
and a lone band at the other. Orient the resistor so the lone band points to the right and the
clumped bands point to the left. The resistor can be read left to right using the guidelines listed
below.
1. The first color band indicates the first digit in the numerical value of the resistance.
2. The second color band gives the second digit in the numerical value of the resistance. Any
subsequent bands before the last band in the "clump" give subsequent digits in the numerical
resistance value.
3. The last color band in the "clump" gives the number of zeros that follow the first digits.
4. The "lone" color band on the right end gives the tolerance.
Note: Tolerance is the amount by which the actual resistance can be different from the
color-coded value and it is given in percent. For example, a 1000 resistor with a +-10%
tolerance can have an actual resistance value between 900 22 and 1100 2. The color codes for
digits and tolerance are given in Figure 1. Your instructor might suggest a convenient mnemonic
which may help you to remember the code.
