So according to the formula the resistance will be: 103 * 100 = 10300 Ohms with 5% tolerance and 100 ppm/K temperature coefficient value Color bands are used to indicate the resistance value with each color signifying a number and these color bands are grouped closer to one end of the resistor than the other. As can be seen in the above 4 Band Resistor Color Codes chart, the first two color bands have values of brown = 1, red = 2, orange = 3 and so on

Yellow, the resistor's value is in hundreds of thousands of ohms. Green, the resistor's value is in megohms. Blue, the resistor's value is in tens of megohms or more. Although you may find any of the above colors in the third band, red, orange, and yellow are the most common. In some cases, the third band will be silver or gold With our math done, we now know that with a 5% tolerance our 550 ohm resistor has a minimum resistance of 522.5 ohms and a maximum possible resistance of 577.5 ohms. 5-Band Resistor. Our second example resistor showcases a 5-band color resistor. The main difference between this resistor and the 4-band resistor is the addition of the 3rd digit

This is a resistor with color bands. red-red-red-gold, has the value:a. 22000-45%b. 2200+5%C. 220+5%d. 2015%4 7 10000000 0.10% Gray 8 8 100000000 0.05% White 9 9 1000000000 Gold 0.1 5% Silver 0.01 10% No Color 20% For example take the following resistor which has bands Green, Blue, Yellow, and Gold. Since there are four bands the third band is the multiplier and the fourth band is th

Resistor Color Code Chart and Standard Resistor Values

Read approximate value from color coding or set to a medium value. Hold two probes against the resistor's two legs on a flat non-conductive surface. If the reading comes in decimal like 0.19, then you can move the dial of multimeter to the next lowest value written on the multimeter. It will become like 187 Orange, White, Yellow. 39 with 4 zeros after it is 390,000 ohms. For resistors less than 10 ohms the gold and silver colors appear in the third, C, band. A gold third band means A.B is the number of ohms. A silver third band means 0.AB ohms. For example Green, Blue, Gold. This is a 5.6 ohm resistor. Red, Violet, Silver. This is a 0.27 ohm resistor So there are several resistors in a circuit i am trying to replicate and i am having trouble deciphering the final values to each one. i am using the hobby-hour.com resistor calculator and a resistor band value chart as reference but i am still in a world of confusion. first off, on all the resistors except the 4 band white one, it seems that all the bands are all spaced out evenly among the. Formula for 5 Band Resistor Calculator. 1 st Digit . 2 nd Digit . 3 rd Digit x Multiplier; ± Tolerance in %. For example, the value of resistance for shown 5 band resistor color code ( Brown, Black, Orange, Red and Yellow) according to the table would be: 1 . 0 . 3 x (100) = 10.3 kΩ with ± 5% Tolerance 2nd stripe: yellow = 4 3rd stripe: green = 5 4th stripe: orange = 10 3 5th stripe: blue = ± 0.25% 6th stripe: red = 50 ppm/ o C so its resistance is 245 x 10 3 ± 0.25% with 50 ppm/ o C Ω or 245000 ± 0.25% with 50 ppm/ o C Ω or 245 ± 0.25% with 50 ppm/ o C kΩ or 245 ± 0.6125 with 50 ppm/ o C kΩ or 244.3875 ~ 245.6125 with 50 ppm/ o C kΩ or 244.3875 ~ 245.6125 kΩ with no more than 50.  A 4 (four) band color code resistor has 4 (four) bands, 1 st indicating the first significant digit, 2nd band indicating the second digit, 3rd multiplier and 4th tolerance. This calculator is used to find the resistance and tolerance value based on the color codes. First Band Color. Brown Red Orange Yellow Green Blue Violet Gray White Your code for determining the significant figures in your resistor value is quite a bit more complex than needed. Since you declare the global array of struct item_list, all you need to do to form the significant figure is to use item_list as a lookup-table to find the index for the band-color entered. For each subsequent color (2nd [and 3rd for 5-band]), you simply multiply the current. standard color coding method for resistors uses a different color to represent each number 0 to 9: black, brown, red, orange, yellow, green, blue, purple, gray, white.Resistor Color Code CalculatorOn a 4 band resistor, the first two bands represent the significant digits. On a 5 and 6 band, the first three bands are the significant digits Using the color code. For example, a resistor with bands Brown Black Orange Blue would have resistance 10×10 3 $\Omega$ (10 000$\Omega$) with a tolerance of ±0.25%. Resistor types Carbon composition. Carbon composition resistors consist of a solid cylindrical resistive element made from a mixture of finely ground carbon and insulating material
