Cable current density

Calculates approximate voltage drop for a simple DC circuit with outgoing and return conductors.

Calculates resistance of a uniform conductor from resistivity, length, and cross-sectional area.

Calculates theoretical wire resistance from resistivity, length and cross-sectional area.

Calculates AWG geometry, resistance, metal mass, and optional voltage drop and power loss.

Helper calculation for cable power loss from current and resistance; it is not an allowable-load assessment.

Calculates simplified voltage drop in a balanced three-phase system from per-length parameters.
