> One, electrical energy does not flow from cathode to anode. Nor does it go the other way. The energy goes down both wires, from source to load.
And it doesn't even "do gown" "the wires" depending on what you mean by that. The energy flux is IIRC the product of E and B fields, which is non-zero only outside the wires.
The wires, in a sense, only acts as a rough guide for the energy, which itself is transmitted through the air/non-conducting surrounding space, and (importantly for some applications) enters the load from its "sides", from the non-conducting space around it, not through the wires.
