I have a question about AC circuits. I've read the whole section of AC circuits in the ebook, but there is still one thing I don't quite understand.
If you have an AC circuit with, say, an infinitely long conductor, how does the current travel down the wire? If the current is moving back and forth, it goes half a cycle (180deg) down the conductor half a wavelength, and then reverses direction and travels back the other half of the cycle half a wavelength, when/how does the current travel the next wavelength down the conductor, and then next, etc.
