Programming Assignment #4: Resistor Color Code Class Background: Resistance is a measure of the opposition of the flow of charge through a material (measured in Ohms, ?). 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 10, with a tolerance (accuracy) of D, where the values of A, B, C, and D are derived from the tables below Bands A, B, and C Color Numeric Value Band D Color Gold Silver None Tolerance 0 ac Brown Red 10% 20% Oran Yellow Green 4 ue Violet Gra White Silver -1 1.
