resistor color code calculator

 To allow for identification, resistors are usually marked
 with colored bands. Often refered to as color codes, these
 markings are indicative of their resistance, tolerance and
 temperature coefficient. gResistor helps 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 colours you'll see that the
 resistor value is changing accordingly.
