A correction - insert dt instead of dz.

Another correction is in order. The resistive term should be i(z) * R
and the conductance term should be v(z) * G.


The fundamental partial differential equations of transmission lines
are -

- dv/dz = R + L*di/dt

- di/dz = G + C*dv/dt

where volts v and current i are incremental functions of distance and
time, and z is incremental distance along line.
