- 4. 1. At firs we have to memorize the color codes of resistance. 2. Then carefully see the color bands of a resistance. 3. Then we will apply the law to identify the value of the resistance. 4. Then we will measure the resistance with the multi-meter. Procedure by Tajim 4
- 6. by Tajim 6 How to read the value of a resistor by reading the color bands? Small resistors are labeled with a color code to show their value.
- 7. by Tajim 7 At first identify the color bands in each resistor. To identify each color in a resistor you must first memorize the color codes. Some resistors have 4 band color codes and some resistors have 5 band color codes and some 6. Memorize them for the mean time, because you are about to calculate the color codes on step 3. Step 1:

- 9. by Tajim 9 How to memorize the color codes of Resistance Bad Boys Ravage Our Young Girls Behind Victory Garden Walls. B B ROY of Great Britain had a Very Good Wife wearing with Gold and Silver Necklace. Bad Beer Rots Our Young Guts But Vodka Goes Well. B B ROY Good Boy Very Good Worker. The green letters indicates the color names those have to be memorized with the code numbers.

- 12. by Tajim 12 Another Calculation: To read the bands you start from the color not the color of the tolerance Now, here is a 4 band resistor. As you can see, the first band starts with a color not the color of the tolerance To calculate, you can see that the first band is Yellow, where the code is 4 (you can see the color codes on step 1). The second band is Violet where the code is 7 Finally the third band is Green where the code is 5, (now read carefully, remember that every color that come before the color of the tolerance is the number of zeros with codes) so now we have green color where the code is 5, so there are five zeros (00000) So, the value of this resistor when you calculate will be: 4700000 ohms where the tolerance is 10% because the color is silver. You can see the color of every tolerances on step 1

- 14. by Tajim 14 Note: The Gold or Silver band is always placed to the right. The resistor value is read from the left to right. If there is no tolerance band, then find the side that has a band closest to a lead and make that the first band.
- 15. by Tajim 15 Step 4: We have learned how to measure an resistance with its color code. We can measure an resistance without memorize the color code and calculating the codes, by the help of an multi-meter. We can attach simply the two terminal of the multi-meter with the resistance and can see the result in meter.
