Transmission lines: deriving the damped wave equation

By considering an infinitesimal part of a transmission line, we derive differential equations for its voltage and current. At the end, we consider how the solutions depend on the capacitance, inductance and resistance (per unit length) of the transmission line and think about the physical interpretation of the results.
About me: I studied Physics at the University of Cambridge, then stayed on to get a PhD in Astronomy. During my PhD, I also spent four years teaching Physics undergraduates at the university. Now, I'm working as a private tutor, teaching Physics & Maths up to A Level standard.

Very interesting and well done, thanks!

Could you do a video about lagrangian points next? Thanks

[@DrBenYelverton]

It's on my to-do list, I will try to get around to this soon!

Hello, could you pls explain why you chose to drop the conductance that is in parallel to the capacitance
