Printable Resistance Tables Sheet
This sheet is for electricians, students, and anyone working with voltage loss calculations. It lists conductor resistance at 75 °C in a simple table with columns for Size, Area mm², Copper Ω/1000 ft, Aluminum Ω/1000 ft, and Copper Ω/km. The rows include common wire sizes such as 14 AWG, 12 AWG, and 10 AWG, with sample values like 14 AWG at 2.08 mm² and 3.0688 Ω/1000 ft for copper.

Use it as a quick reference when checking voltage drop, comparing copper and aluminum conductors, or building hand calculations from resistance data. The values are based on DC resistance from resistivity, and the sheet notes that stranded or coated conductors may vary slightly from manufacturer values.
Good for
- Check conductor resistance before a voltage drop calc
- Compare copper and aluminum wire values quickly
- Reference common AWG sizes during planning
Tip: Print in landscape and keep it with your voltage loss worksheet for faster lookups.
