What Wirecora does
Electronics calculations are most useful when you can connect them to the component in front of you and the circuit you are building.
Wirecora keeps those pieces together. Inputs, units, visual components, calculated results, tolerances, and operating limits stay in one clear view.
The goal is not only to produce the right number. It is to make that number understandable enough to use with confidence.
Built for understanding
See the physical part or circuit relationship behind the numbers, not just an isolated formula.
Keep the inputs, units, method, and result visible so the answer can be checked and understood.
Show tolerance, power, safe ranges, and important warnings before a result is used in a real circuit.
Available now
Decode a 3, 4, 5, or 6-band resistor, or enter a resistance value to find the correct colour bands.
The result stays beside a clear resistor visual, tolerance information, warnings, and a complete IEC colour reference.
