How to Use This Calculator
- Select your conductive thread material (silver-coated nylon, stainless steel, carbon, or copper wire).
- Enter the total thread length (cm), thread diameter (mm), and number of stitch junctions in the circuit.
- Set the contact resistance per stitch (Ω) based on construction quality — typically 0.1–2 Ω.
- Enter wash cycles completed and operating temperature (°C) to account for degradation.
- Review total resistance (Ω), estimated current at 3.3 V, and power dissipation in the outputs.
