Transmission Lines — Lesson 5

This lesson covers the concept of transmission line. It delves into the development of a model for a wire, analyzing how voltage or current propagates through it. The lesson further explains the wave equation, the relationship between voltage and current, and the concept of forward and backward moving waves. It also discusses the impact of resistance and conductance on the wave.
