Chapter 33 Resistor Color Chart

This section of EE•Pro allows the user to enter the color sequence of a

physical resistor and compute its value and tolerance. Most physical

resistors come with a band of colors to help identify its value. There are 3

variations of color bands used in practice: 3, 4 or 5 band of colors. The

table below identifies the hierarchy used in practice. A picture of the

color chart is included in the software and is displayed when the function

key † is pressed.
