EGR 125 Introduction to Engineering Methods (C++) File: N125P4A Programming Assignment #4: Resistor Color Code Class Background: Resistance is a measure of the opposition of the flow of charge through material measured. in Ohms, 2). A resistor is an electrical circuit element that has been manufactured to have a particular value of resistance. Carbon resistors are often color coded using 12 different colors which appear in 4 bands on a resistor, as shown below A B C D The numerical value of the resistance, R, is determined using the four bands as follows: R AB x 10C, with a tolerance (accuracy) of D, where the values of A, B, C, and Dare derived from the tables below. Bands A, B, and C Band D Color Numeric Value Color Tolerance 15% Black Gold 100 Silver Brown 2 None Red 20 Orange Yellow Green 5 6 Blue Violet White -1 Silver -2 Gold Notes 1. Band A may not be black, gold, or silver. 2. Band Bmay not be gold or silver. 1. Yellow, violet, blue, none R 47 x 106 47000000 o (or 47 Mo), 20% 2. Green, brown, red, gold R 51 x 102 5100 o (or 5.1 ks), 5% 3. Blue, green, gold, silver R 56 x 10 5.60, 10%
