Testing and Final Adjustments
Test with various wire sizes, lengths, currents, and voltages. Validate calculations against standard voltage drop formulas:
- Voltage Drop (V) = 2 × L × I × R (single-phase, one-way resistance formula)
- % Drop = (Voltage Drop ÷ Supply Voltage) × 100
Check both copper and aluminum wires. Include error handling for invalid or missing inputs. Test mobile and desktop responsiveness. Provide instant calculation updates. Display results clearly with proper units. Include guidance for entering values correctly. Optimize UI for speed, clarity, and accuracy. Include support for both single-phase and three-phase systems if needed. Round results appropriately for practical use.
