Telegrapher's equations

Oliver Heaviside developed the transmission line model, also known as the telegrapher's equations, that describes how electrical voltage and current vary along a conductor.

The theory applies to high-frequency transmission lines (such as telegraph wires and radio frequency conductors) but is also important for designing high-voltage energy transmission lines.

The equations consist of two linear differential equations in time and position: one for V(x,t) and the other one for I(x,t). The model demonstrates that the electrical current can be reflected on the wire, and that wave patterns can appear along the line.
