This application will help you to calculate resistance of resistor by resistor color code.
However, this application only can calculate four or five lines resistors.
Top-to-Bottom sequence: First 2-3 lines are band, last two lines are multiplier and tolerance.
Bottom-to-Top sequence: Reverse of Top-to-Bottom.
You can just put values in the top-to-bottom or bottom-to-top.
If it's invalid sequence in some way, it will automatically reverse it.
It will automatically skip "None" colored line.
If your input is a valid sequence in both ways, it will calculate by top-to-bottom sequence.
In this case, you should check standard resistor value table.
