Frequently Asked Questions
-
What does an ohm inch represent?
-
An ohm inch quantifies electrical resistivity as the resistance of a one-inch long specimen with a one square inch cross section.
-
Why is circular mil ohm/foot used in electrical wiring?
-
Circular mil ohm/foot measures resistivity relative to conductor dimensions common in wiring, helping calculate resistance based on length and cross-sectional area.
-
Can this conversion be applied to all conductor shapes?
-
No, it assumes standard geometric conditions; non-uniform shapes might require adjusted calculations.
