>I'm pretty certain a lot of this is wrong.
well as long as youre certain
>Yes it does
if you agree that the only way to move an electron is via the electromagnetic field, and if you agree that electrons move in a circuit in an AC generator, then you cannot conclude that generators follow KVL. is it possible for a roller-coaster train to perpetually move through its circuit if the only force to propel it is gravity?
>It does provide current. some signal to antenna setups can power a speaker off the signals they pick up
emphasis on ideal. and you cant have it both ways, either it doesnt provide current or it violates KCL. or do you think its grabbing charge from the air?
>There is current going in and current going. Which for circuit design is the same. But perhaps you are right on this
you can charge/discharge one side of a capacitor without (dis)charging the other one. in a circuit diagram you would hand-wave this as a second capacitance to ground.
>How? They sometimes have voltage across and sometimes don't. This is not in conflict with KVL
see AC generator note above
>Yes they do. The same way magnets "push" on each other
if you fire two electrons at each other they will indeed bounce off one another, but thats not whats happening inside a wire. electricity isnt a tube of marbles where you push one in at one end and another pops out at the other end. the space between free electrons in a conductor is gargantuan compared to their size (well, "size").
