![]() Capactors, Zener diodes, and inductors also use these standards. These are referred to as preferred values or E-series, published in standard IEC 60063:1963. Preferred Values or E-seriesTo make mass manufacturing of resistors easier, the IEC (International Electrotechnical Commision) defined tolerance and resistance values for resistors in 1952. When you see only three color bands on a resistor, you know that it is actually a 4-band code with a blank (20%) tolerance band.A resistor colored Orange-Orange-Black-Brown-Violet would be 3.3 kΩ with a tolerance of +/- 0.1%.A resistor colored Brown-Green-Grey-Silver-Red would be 1.58 Ω with a tolerance of +/- 2%.A resistor colored Blue-Brown-Green-Silver-Blue would be 6.15 Ω with a tolerance of +/- 0.25%. The blank (20%) “band” is only used with the “4-band” code (3 colored bands + a blank “band”).A resistor colored Yellow-Violet-Orange-Gold would be 47 kΩ with a tolerance of +/- 5%.A resistor colored Green-Red-Gold-Silver would be 5.2 Ω with a tolerance of +/- 10%.A resistor colored White-Violet-Black would be 97 Ω with a tolerance of +/- 20%. All 5-band resistors use a colored tolerance band. The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only. Standard Resistor Values and ColorComponents and wires are coded with colors to identify their value and function. If the user say 'y' or 'Y', the program shall show the color code menu and wait for input.Try out our Resistor Color Code Calculator in our Tools section. Once the output is displayed, the program shall ask the user if he/she wants to continueħ. value in giga-ohms if the last color is white or greyĦ. value in Mega-ohms if the last color is green, blue or violet. value in kilo-ohms if the last color is red, yellow or orange. Output: value is in ohms if the last color is black or brown. If all three letters are valid, the program shall output the resistanceĥ. If the input is invalid (letters are case insensitive), the program shall say "Invalid Input" and re-print "enter valid input" and wait for responseĤ. The program shall wait for the user to input three lettersģ. Upon start-up, the program shall display a color code menuĢ. Write a program that will provide the user a color code menu, the user will then enter the three letter codes that correspond to the three color bands and the program will output the resistance value in ohms.ġ. ![]()
