Directional wires/cables

The Energy travels from the source >>> to the load (in one direction)

Okay, I got a simpler question, what if the load is disconnected before the energy gets there, what happens to that energy?

It breaks the circuit. No circuit, no energy transfer, flow.

What happens when you flip off a light switch? Light goes off immediately.

This may help you understand what’s going on.

jea48....  I was making a bad joke about the question you raised....

"If the speakers were 3251 kilometres away would there be no signal- would the energy simply stop and turn back the other direction, and one would hear no sound from the speaker?"

I completely botched it up... not @jea48, but rather @mclinnguy....

I'm going to shut up now...

What happens when you flip off a light switch? Light goes off immediately.

I would interpret "immediately" to mean small fractions of a second after flipping the switch, after the energy in the lines has completely been absorbed by the load.

Just questioning the "one way direction" of energy in an alternating current conductor, but that’s fine.

If it's designed directional, it should have arrows on it. It's that simple.

If the vendor claims it is directional and does not indicate the correct direction, that's a clear design defect and I would find another vendor.
