Volts AC
Notebook = 44
Scales a size-graduated density curve — fine secondary/control wire is allowed proportionally more A/mm² than the heavy primary wire, matching real winding heat dissipation.

1. Core Strip Width (cm):
(10.0 - 5.0) ÷ 2 = 2.50 cm
2. Core Cross Area (Ac):
2.50 cm × 7.0 cm = 17.50 cm²
3. Turns Per Volt (TPV):
44 ÷ 17.50 = 2.514 turns/volt
4. Primary Turns (Npri):
220V × 2.514 = 553 turns (Notebook benchmark: 550)
5. Mean Turn Length (MLT):
2 × (2.5 + 7.0) × 1.12 = 21.28 cm / turn
6. Total Wire & Weight:
