The other day, a friend and I were looking at a simple resistor-capacitor-inductor circuit. As we were looking at the circuit, he mentioned that the capacitors and inductors "talked" to each other through the air. From this, I assume he meant that the capacitors and inductors were exchanging EMF waves, and that it was an essential part of how these circuits operated.
I was surprised by this because I didn't remember learning about this in my circuits class, but it made some sense because I figured every electronic device is emitting some sort of EMF wave. I just always assumed these were of minor importance to the circuit.
My question is how do these circuit elements communicate with each other in simple RCL circuits? Is it primarily through the voltage/current local to the wires, or are there important EMF considerations.
To clarify, I understand that at some level, the voltage/current in the wires is being controlled through EMF waves since that is how the charge of an electron is communicated to near by electrons. I am referring to EMF waves here to be over macroscopic distances (between circuit elements).
