A free program for Android, by Tom Hogenkamp.
This app is a color code calculator for calculating the resistance of a resistor. The application can calculate the color code for 3, 4, 5, and 6-band resistors.
The app can calculate the resistance of any value from an input value.
It has an extensive list of standard values for resistance, including values for copper, aluminum, gold, silver, and more.
The app has a list of the most commonly used colors for a resistor, which include black, brown, red, orange, yellow, green, blue, violet, grey, white, gold, and silver.
