  • CALCULLAWire resistance calculator

    By the wire resistance we mean the resistance of the conductor as a whole. This is a value that we can directly measure with an ohmmeter by applying its probes on both sides of the wire. The total resistance of the wire depends on type of material the wire is made offor example copper conducts electricity better than lead temperaturethe ability to conduct electric current of various

  • Transmission Line Parameters Resistance and Inductance

    The conductors of the transmission lines have small resistance. For short lines resistance plays an important role. As the line current increases so do the ohmic loss (I 2 R loss). When the current exceed a certain value the heat generated due to ohmic loss starts to melt the conductor and the conductor becomes longer that results in more sag.
