Default Current through coils

Richard Harrison wrote:
A transmission line can`t be analyzed as a simple series circuit,
because the current in the wires is not everywhere the same. Neither is
the voltage. To analyze the line, each unit length must be examined.

Each unit length produces a phase lag in the current on its wires. The
voltage lags too. This can be totaled and the interference between the
incident and reflected waves deternined to find the voltage and current
at any point on the transmission line,


Yes, and that also applies to a real-world loading coil installed
in an environment of incident (forward) and reflected (backward)
waves. Why this is so difficult for some people to understand
is puzzling. All one has to do is use the superposition principle.
Analyze the forward wave, analyze the reflected wave, and superpose
the results.
