I am wondering what exactly is happening when you transmit a frequency through a wire at an electron level. How do the electrons make a sine wave for example. I understand you can make an oscillator then what seems to be magic at this point a sine wave is transmitted down the wire. What are the electrons doing to make the frequency. I don't know if the wire is the best place to work for this but that's where I thought of it. Would I need to go back to oscillators to try and figure this out or did I miss something easy or am I over complicating it?
