Sikui elektrik yo prezante tou diskontinwite ki afekte pwopagasyon vag; nan kontèks sa a, paramèt kritik la se enpedans. Imajine yon vag elektrik vwayaje desann yon liy transmisyon; sa ekivalan a vag dlo nan mitan lanmè a. Vag la ak enèji ki asosye avèk li yo ap pwopaje san pwoblèm soti nan sous chaj. Evantyèlman, menm si, vag elektrik la rive nan destinasyon li yo: yon antèn, yon anplifikatè, elatriye.

Electrical circuits also present discontinuities that affect wave propagation; in this context, the critical parameter is impedance. Imagine an electrical wave traveling down a transmission line; this is equivalent to the water wave in the middle of the ocean. The wave and its associated energy are propagating smoothly from source to load. Eventually, though, the electrical wave reaches its destination: an antenna, an amplifier, etc.
