ResistanceApp is an application that allows you to identify the value of 4-, 5-, or 6-band resistors according to the electronic standard. Select the color of each band and instantly display the resistor's value, as well as the upper and lower tolerance values, its value in KOhms, MOhms, or GOhms, and the temperature coefficient for six-band resistors.

Select the color of each band individually, and the app will calculate the value of your resistor. You can select from the number of available bands and also find values ​​such as the upper and lower tolerances when measuring the resistor to determine if it's suitable for your electronic circuit.
