Calculation method
Calculation method
Resistance (Ω)
a × b ÷ (c ÷ 1e6)
Symbols and units
- a
- Resistivity (Ω·m)
- b
- Length (m)
- c
- Cross-section (mm²)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Use resistivity at the actual operating temperature. This does not determine safe current capacity.
