Does current depend on area
Webtance = voltage/current). The conductance of the solu-tion is the reciprocal of the resistance. The ionic current depends on the total concentration of ions in solution and on the length and area of the solu-tion through which the current flows. The current path is defined by the sensor geometry, or cell constant, which has units of 1/cm ... WebSep 12, 2024 · The current density \(\vec{J}\) that results depends on the electrical field and the properties of the material. This dependence can be very complex. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as

But if the feeder is not sized correctly (cross-sectional area), say supplying a 10hp motor at 250ft, the load may be affected to an extent that the load does not operate correctly. Too much voltage is lost to the feeder.
