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.
