Technical Documentation

Calculation Methodology

CoilCalc uses industry-standard formulas for electrical resistance calculations:

• Resistance: Based on wire material resistivity, length, and cross-sectional area
• Power: Calculated using Ohm's Law (P = V²/R or P = I²R)
• Current: Derived from voltage and resistance (I = V/R)
• Heat Flux: Considers wire surface area and power delivery

Supported Wire Materials

• Kanthal A1
• Nichrome (Ni80, Ni90)
• Stainless Steel (SS316L, SS304, SS317L)
• Nickel (Ni200)
• Titanium (Grade 1)

Code Quality

The project maintains high code quality standards:

• Kotlin coding conventions
• MVVM architectural pattern
• Comprehensive input validation
• Safety-first approach to calculations
• Regular dependency updates
