This page intentionally left blank The Resistor Color Code Band color Numeric value Black Brown Red Orange Yellow Green Blue Violet Gray White 0 1 2 3 4 5 6 7 8 9 1st number Multiplier 2nd number Tolerance band (e.g. gold = 5% silver = 10%, none = 20%) 1. Write down the numeric value corresponding to the first band on the left. 2. Write down the numeric value corresponding to the second band from the left. 3. Write down the number of zeros indicated by the multiplier band, which represents a power of 10 (black = no extra zeros, brown = 1 zero, etc.). A gold multiplier band indicates that the decimal is shifted one place to the left; a silver multiplier band indicates that the decimal is shifted two places to the left. 4. The tolerance band represents the precision. So, for example, we would not be surprised to find a 100 5 percent tolerance resistor that measures anywhere in the range of 95 to 105 . Example Red Red Orange Gold Blue Gray Gold = 22,000 = 6.8 or 22 ×103 or 68 ×10−1 = 22 k, 5% tolerance = 6.8 , 20% tolerance Standard 5 Percent Tolerance Resistor Values 1.0 1.1 1.2 1.3 1.5 1.6 1.8 2.0 2.2 2.4 2.7 3.0 3.3 3.6 3.9 4.3 4.7 5.1 5.6 6.2 6.8 7.5 8.2 9.1 10. 11. 12. 13. 15. 16. 18. 20. 22. 24. 27. 30. 33. 36. 39. 43. 47. 51. 56. 62. 68. 75. 82. 91. 100 110 120 130 150 160 180 200 220 240 270 300 330 360 390 430 470 510 560 620 680 750 820 910 1.0 1.1 1.2 1.3 1.5 1.6 1.8 2.0 2.2 2.4 2.7 3.0 3.3 3.6 3.9 4.3 4.7 5.1 5.6 6.2 6.8 7.5 8.2 9.1 k 10. 11. 12. 13. 15. 16. 18. 20. 22. 24. 27. 30. 33. 36. 39. 43. 47. 51. 56. 62. 68. 75. 82. 91. k 100 110 120 130 150 160 180 200 220 240 270 300 330 360 390 430 470 510 560 620 680 750 820 910 k 1.0 1.1 1.2 1.3 1.5 1.6 1.8 2.0 2.2 2.4 2.7 3.0 3.3 3.6 3.9 4.3 4.7 5.1 5.6 6.2 6.8 7.5 8.2 9.1 M TABLE 14.1 Laplace Transform Pairs f(t) = 5−1 {F(s)} δ(t) u(t) tu(t) n−1 (n −1)!u(t), n = 1,2,... e−αtu(t) te−αtu(t) n−1 (n −1)!e−αtu(t), n = 1,2,...
