Homework assignment - find me one audio circuit that's not AC.
Follow Ups:
That's not what I asked you though. :)
'Try to stay focused.
Dave.
So many questions. Isn't the answer obvious? Would one terminal on the speaker work?
So your answer is "no"? :)
Dave.
I'm waiting for you to give me an exception to the rule. I never say never. Cable manufacturers would undoubtedly be elated to hear they couid now make audiophile cables using only one wire. Audiophiles would rejoice, prices would be cut in half.
"Two wires are required to make an AC circuit." Was that not your quote?
Dave.
You're hot dogging me, right? If you're pretending to be obtuse you're doing an excellent job.
It only appears obtuse, to you.
Dave.
So, Mr. Smarty Pants, have you found anything to dispute what I've said? No, of course you haven't.
Isn't an antenna a single wire AC 'source'?
Too much is never enough
An Antenna uses a ground plane, that's your second wire.
"In antenna theory, a ground plane is a conducting surface large in comparison to the wavelength, such as the Earth, which is connected to the transmitter's ground wire and serves as a reflecting surface for radio waves."
DC circuits also require a second wire.
For work to be done, a complete circuit is required.

You don't need two wires to have a circuit....technically. :)
You need two potentials to create a source, but you can connect those two with a single wire/circuit.Your house has numerous appliances that consist of single wire element that operate on AC.
In fact, the standard amplifier/speaker interface is actually a single wire series circuit. It might not look like one, but it is. (Ignoring the minor intrinsics of the connection cable.)
The illustrious Mr. Kait will accuse me of semantics, but I don't give a shit what he says.

But we're talking about audio, not home appliances. Duh! Pseudo skeptics will try to argue any absurd point.
It's all basic electricity dude. It doesn't matter whether it's audio or not.
Get thee to an Electronics 101 class, pronto.
Dave.
That's what all pseudo skeptics say, dude.
