In circuits this energy is usually returned to the circuit when the field collapses. If the field does not fully return its energy to the circuit, the wave is partially radiated, or set free, from the circuit.

WebOnly EM waves travel this fast. Another way to look at things is that the voltage at a location on the wire is just a simpler way of looking at the fact that there is an electric field between the wire and everything around it. When a signal propagates along a wire, it's actually the electromagnetic field between the wire and a nearby "ground ...
