Resistor Calculator

Resistor Calculator is a practical electronics utility for quickly decoding resistor values, checking color bands, converting resistance values into band colors, and reading SMD resistor codes.

The app is useful for electronics students, hobbyists, makers, repair specialists, and anyone working with circuits or electronic components.

Features:

• Band Calculator
Select 3-band, 4-band, or 5-band resistors and instantly view the resistance value and tolerance.

• Reverse Calculator
Enter a resistance value and get the corresponding resistor color bands.

• SMD Decoder
Decode 3-digit and 4-digit SMD resistor markings quickly and clearly.

• Calculation History
Review previous band calculations, reverse lookups, and SMD code checks in one place.

• Clear Results
See resistance values, tolerance, and color-band information in an easy-to-read format.

Resistor Calculator helps reduce guesswork when working with components. Whether you are assembling a project, repairing electronics, studying circuit basics, or checking a resistor at your workbench, the app gives you a fast and reliable reference.

Open the app, enter the value or select the bands, and get the result in seconds.
