App Launch
This application was developed for reading fixed resistors, also called through-hole resistors, carbon resistors, carbon film or metallic film.
Choose the colors and discover the resistance.
This calculator makes it easier to accurately read resistors with colored bands, their value and their tolerance (margin of error).
There are resistors of up to 6 bands of colors, but the most common are those of 4 and 5 bands.
Our application aims to help hobbyists, students and even professionals in electronics in an easy and practical way to identify a specific resistance value.
