Query: Simple and accurate method to simulate resistors and wires in a
  nanoscale circuit   In solving the Schr\"odinger equation to simulate a nanoscale circuit, we
note that the mean free path for electrons in some metals is as large as 48 nm.
Thus, the wavefunction may propagate coherently through wires corresponding to
the lines that show the potential outside of the tunneling junction. A voltage
source may be modeled as a jump in the potential. Similarly, the potential
across a resistor may be modeled as a sharp drop or a downward sloping line to
show a decrease in the potential. Then the resistance may be determined by
dividing this voltage drop by the product of the calculated current density and
the effective cross-sectional area.
