>>13932286you fail to understand causation. The power doesn't stop propagating because the copper isn't there. The power stops being delivered because there is an abrupt discontinuity in the impedance. power is transmitted in the fucking air all day everywhere. How do cell phones work? how does radio work? where are the fucking wires? You got filtered because you can only comprehend electricity as direct current in the steady state. EM is a hell of alot more than Ohms law, moron.
