I was reading in my electronics book the other day. I just finished up a lesson on DC current and it was all good. But then came the lesson on AC current and I am stuck. I There are a few concepts of AC current as well as some parts that require AC current that I do not completely understand.
1)What the heck is the wave "Shape?" I heard it was like the shape the AC current makes when you put it on a graph or something.
2)Does a crystal take in DC and give off AC at a specific frequency, or does it take in any AC with any frequency and change it to AC at a specific frequency.
3)If it does take in AC, does the crystal change the "shape" of the AC current?
I also heard about this wonderful thing called and oscillator that is suppose to turn DC into AC or something like that. I have not found a simple oscillator design yet(Not sure if one exists) so I was not able to try any experiments. Anyways, If a battery gives of DC at the negative terminal, how can it take in AC at the positive? If anyone could find/make an oscillator schematic that is so simple a caveman can do it, that would be awesome.
