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. 4-Band-Code N 2%, 5%, 10% 560kQ+ 5% 1st BAND COLOR Black 0 Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Violet 7 Grey 8 White 9 Gold Silver 0.1%, 0.25%, 0.5%, 1% 5-Band-Code Electronix Express/RSR http://www.elexp.com 2nd BAND 0 1 2 3 4 5 6 7 8 9 3rd BAND 0 1 2 3 4 5 6 7 8 9 חוה MULTIPLIER 10 10Q2 1000 1KQ 10KQ 100ΚΩ 1MQ 10ΜΩ 0.1 0.01 TOLERANCE (F) (G) (D) (B) (1) (K) 1-800-972-2225 In NJ 732-381-8020 01 (Image courtesy http://www.elexp.com) Figure 1.
