Resistor value calculator

Quickly, accurately, and effortlessly calculate electrical resistor values with this professional calculator. Ideal for students, engineers, and electronics hobbyists.

The application features a modern two-tab interface for all your calculation needs:

1. COLOR ➔ VALUE (Color to Value)
Select the band colors directly on the on-screen resistor to instantly find its value in Ohms, tolerance, and series classification. Supports 3, 4, 5, and 6-band resistors.

2. VALUE ➔ COLOR (Value to Color)
Enter the numeric value of the resistor (Ohm, kΩ, MΩ, GΩ), select its series classification, and optionally the temperature coefficient to instantly discover the corresponding color combination.

Key Features:

- Full support for 3, 4, 5, and 6-ring resistors.

- Commercial series validation: instantly checks if the entered value belongs to standard E6, E12, E24, E48, E96, or E192 series.

- Tolerance limit calculation: instantly displays the real Minimum and Maximum resistance values.

- Quick sharing: share complete calculation summaries and series details via WhatsApp or email with a single tap.

- Quick Reset: A handy Reset button allows you to instantly clear the calculated values in the active tab.
