To allow for identification, resistors are usually marked with colored bands.
Often referred to as color codes, these markings are indicative of their
resistance, tolerance, and temperature coefficient. gResistror is a great
program that will help you translate resistor color codes into a readable
value. All you have to do is watch the colors on the resistor and then
enter them in the program. As you enter, you'll see that the resistor
value is changing according to the selected color.
gResistor uses Python distutils for installation.
To install gResistor you'll need to have root privileges to make this install.
Type 'python setup.py install' in a terminal.
Run the program
To run the program just type 'gresistor' or click the icon in 'Applications>Accesories>gResistor'
