Standing-Wave Current vs Traveling-Wave Current
Richard Harrison wrote: Someone wrote: "The energy in canceled waves is why the forward power is often greater than the source power." Bird says: "Power delivered to and dissipated in a load is given by: Wl = watts into load = Wf - Wr" Best regards, Richard Harrison, KB5WZI Good point, Richard. Wf = Wl + Wr. Amidst all this consternation about conserving the energy in canceled waves, we should not lose sight of the fact that it is *reflections* (not canceled waves) which cause forward power to measure greater than power dissipated in the load. ac6xg |
