About this app

OhmBand turns the color bands on a resistor into a value you can use. Point at a part, pick the bands, and get the resistance, tolerance, and the range it can actually measure.

Decode 4-band, 5-band, and 6-band resistors, including temperature coefficient
Look up a target value and see the color bands to buy or stock
Decode SMD markings: 3-digit, 4-digit, R-decimal, and EIA-96 codes
Calculate series and parallel networks, voltage dividers, and LED current-limit resistors
Practice with a quiz, keep a favorites list, and check the full color chart
Read a short guide to band order, tolerance, E12/E24 values, and Ohm's law
