Home electrical wiring systems can be conceptually represented as a single-phase, two-wire, lossless transmission line.

These begin at the transmitting end, where power enters from the main grid with a specific voltage and impedance. At the receiving end, appliances and devices, each with a unique impedance, utilize this power as loads.

Boundary conditions are set to dictate how the voltage and current behave at both ends of the wiring system.

The receiving-end voltage equals impedance times its current. Solving this equation introduces the receiving-end voltage reflection coefficient, where transit time is the time a wave takes to travel the length of the wire.

Utilizing the established voltage and current relationships, modified expressions are obtained.

The transmitting end's boundary condition is set by the gap between the source voltage and the impedance-current product.

This relationship yields an expression in terms of the forward-traveling voltage wave.

Upon solving this expression, a coefficient reflecting the voltage at the sending end is established.

With the integration of this into the voltage and current relationships, a comprehensive solution is derived.
