Problem: Could you please show me how to derive the telegraph equations for a loss-less transmission line?

I will use the symbol "d/dx" for the first partial derivative with respective to x and "d^2/dx^2" for the second partial

derivative with respective to x.

Let Rp = Resistance in Ohms per Unit Length,
L = Inductance in Henry per Unit Length
C = Capacitance in Farads per Unit Length
G = Conductance in Siemens per Unit Length.

Then, the line voltage V(x) and the current ...
