- TL;DR Summary
- Are voltage and current waves in transmission lines an artifice or a consequence of electromagnetic waves?

The operation of a transmission line is based on the axial propagation of electromagnetic waves between the two line conductors. However, the study of the transmission lines does not focus on E and B waves but on voltage and current waves.

It is considered that there are resistance, conductance, inductance and capacity distributed throughout the Length of the line conductors. This causes the instantaneous voltage and current values at points of the line to be dependent on both distance and time, that is, they are waves. There are therefore voltage and current waves spreading along the line. The E and B fields are forgotten by the greater ease of the use of voltage and current.

My question is: are the voltage and current waves approach in a line characterized by distributed R, L, G, and C an artifice that ensures

Thanks in advance to all the answers.

Kind regards;

**electromagnetic equivalence**to the existence of E and B waves, or it is a consequence of the E and B Waves E and B that coexist with them?Thanks in advance to all the answers.
