north central Oklahoma | Actually, Brandon, your graph ain't quite right either. The line should be half way through each sin wave, that straight line ain't the neutral. The neutral is a separate line. The A/C sign wave crosses the straight line each cycle. If I could draw and put it on here I would, but I can barely post pics from camera.
The principle of a/c is that is shifts directions 60 times per second, half the wave above the line, half the wave below the line, the distance from peak to peak is a complete cycle. We accomplish getting d/c power by knocking off one half (top or bottom) of the wave with diodes, uni-directional current blocks. In 220 systems, there is two complete 110 volt cycles/graphs and one single neutral.
I know just enough about electricity to get myself killed, and by the looks of most on here, I am not alone.
Edited to fix the word "pump" in title. Just buggin' me to death.
