Ifomula Yokubala Idatha
| 1 | Ifomula yokuguqulwa kwesisindo nobude be-Copepr enamel | I-L/KG | L1=143M/(D*D ) |
| 2 | Ifomula yokuguqulwa kwesisindo nobude be-Wire engunxande | g/L | Z=(T*W-0.2146*T2)*8900*1000/1000000 |
| 3 | Indawo enqamulelayo ye-Rectangular Wire | mm2 | S=T*W-0.2146*T2 |
| 4 | Ifomula yokuguqulwa kwesisindo nobude be-Litz Wire | I-L/KG | L2=274 / (D*D*2*Imicu) |
| 5 | Ukumelana kwentambo engunxande | Ω/L | R=r*L1/S |
| 6 | Ifomula 1: Ukumelana ne-Litz Wire | Ω/L | R20=Rt ×α×103/L3 |
| 7 | Ifomula 2: Ukumelana ne-Litz Wire | Ω/L | R2(Ω/Km)≦ r×1.03 ÷s×at×1000 |
| L1 | Ubude(M) | R1 | Ukumelana (Ω/m) |
| L2 | Ubude(M/KG) | r | 0.00000001724Ω*㎡/m |
| L3 | Ubude (KM) | R20 | Ukumelana komqhubi nge-1km ku-20°C (Ω/km) |
| M | Isisindo (KG) | Rt | Ukumelana ku-t°C (Ω) |
| D | Ububanzi(mm) | i-αt | Isilinganiso Sokushisa |
| Z | Isisindo(g/m) | R2 | Ukumelana (Ω/Km) |
| T | Ubukhulu (mm) | r | Ukumelana kwentambo yethusi ene-enamel engu-1 meter |
| W | Ububanzi(mm) | s | Imicu (izingcezu) |
