The 4 color bands on the left side are grouped together to represent the resistance value of a resistor and the 5 th color band on the right side indicates the tolerance of the resistor the 1 st color band indicates the 1 st significant value or 1 st digit of the resistors value the 2 nd color band indicates the 2 nd significant value or 2 nd digit of the resistor value. They are certainly helpful for any techie smart with their hands. Resistors can be integrated into both hybrid and printed circuits. Izmir university of economics eee 205 fundamentals of electrical circuits lab experiment 1 resistors resistors of differerent tal film resistor. The industry standard resistor color code is used to identify the resistance value of resistors used in all kinds of electronics.
Resistor values are often indicated with color codes.
