The currents are referenced to the source. When the forward current and reflected current are in phase at zero degrees, they are at a maximum and flowing toward the load so their sum, the net current, is flowing toward the load. 1/2 cycle later, the forward current and reflected current are in phase at 180 degrees so their sum, the net current, is flowing toward the source. (snip) Hi Cecil, Actually, net current doesn't flow at all in a standing wave. Current is the rate of change of charge, dQ/dt. In a standing wave, the rate stays put. The charge may be vibrating wildly at a point, but the average rate of change (or even the peak, if that's what's important to you) doesn't move. If it does move, the wave is a traveling wave, not a standing wave. If you were right, then the rate of change of charge would alternately move into and out of your miraculous coil. In other words, there would be an oscillating traveling wave moving first one way and then another, into and out of the coil, and it would do so at both ends, as in some particularly lurid, x-rated movie. This is what happens when you don't understand the math, Cecil. You make stupid mistakes based on a faulty understanding of the fundamentals. I hate to be a fundamentalist like your minister, but I'm sure beginning to appreciate his approach. 73, Tom Donaly, KA6RUH |
