Hello everyone,,
So I know a little bit about electronics. Ohm's law, power law, series/parallel circuits, resistors and capacitors, etc.
One thing I just never understood was how a radio transmitter works, and how a radio receiver works.
One thing that has always bothered me is that we always learn that electrical current follows the path of least resistance. So if there is this random antenna wire hanging off this https://showbox.bio/ https://tutuapp.uno/ https://vidmate.vet/ circuit, why does the signal travel down and get broadcast?
Edit: I'm not asking about AM/FM. I know exactly what they are. My question is how do you produce an electromagnetic wave using just a closed circuit?
