Frequently Asked Questions
- What does ampere per square inch measure?
- It measures electric current per unit surface area, representing how much current flows through one square inch of a surface.
- Why convert to ampere per circular mil?
- Converting to ampere per circular mil relates current density to conductor cross-sectional area, helping with wire sizing and ampacity calculations.
- Can this tool be used for non-uniform current distributions?
- No, the conversion assumes uniform current distribution and ideal unit conditions, so non-uniformities are not accounted for.
Key Terminology
- Ampere per square inch [A/in²]
- A unit of surface current density measuring electric current flowing per one square inch of area.
- Ampere per circular mil
- A unit expressing current per cross-sectional area measured in circular mils, used for conductor current capacity.
- Circular mil
- A unit of area equal to the area of a circle with one mil diameter, commonly used in wire sizing.
