Hi Gib... and yea, I probably used it to illustrate my point incorrectly. A PSU (Power Supply Unit) does convert the 120V AC that comes from the wall to DC current (12v, 5v, 3.3v).
Because I'm not an electrical engineer, I'm not qualified to go into depth about electricity. However here is my feeble attempt.... One of the prime differences between AC and DC currents is that the current is Alternating in AC, meaning that (in America for example) the positive and the negative alternate 60 times a second. DC current the positive is always positive and negative is always negative.
However that only talks about the flow, not the magnitude of the current. And it's the rising and falling of the magnitude of the current where DDR operates. If you want more in depth than that... your gonna have to go see your electrician  |
