Resistor Colors Calc is great for determining resistance using the bands of color on resistors. Select the color of each band you are needing and you are shown the resistance, tolerance, and temperature coefficient of your resistor.
Great for finding out what resistance a given resistor is without having to look up a table of color values. Supports 4 band, 5 band, and 6 band resistors.
