Diagnose
This tool does not attach diagnose observations.
Assumptions
- Uniform linear resistance along the given length.
Provenance
- Total resistance from resistance per unit length.
Pipeline Linear Resistance
Resistance per unit length of the pipe metal from electrical resistivity and metal cross-section. Not soil resistivity or coating conductance.
Rectifier Circuit Resistance
Effective operating circuit resistance from DC voltage and current. For a shunt millivolt rating, use Shunt Value.
