Directional speaker cables - switching direction

So if energy flows in one direction, which direction
does it flow?
+ to - or - to + ?

From source to load independently of polarity.

.....,are you a electrical engineer?

No, but I did stay at a Radisson Inn once.

I must have lead a sheltered life until 5-17-10 when I read a response by Herman to a thread here on Agon. My first thought was, what planet is this guy from?

The Thread.

I believe Kijanki has a degree in electrical engineering or physics, or both.

Al, Almarg, is also an electrical engineer.

Herman used to teach the theory.

Jea48, thanks for the link to the 2010 thread. That was a wonderful trip down memory lane.

It's a shame we don't see discussions of that caliber here anymore.

Thanks for quoting me...
Sure cables can sound different. Crappy ones sound different from good ones. There is no magical synergy with a speaker or amp though. The cables purpose to to move the energy (voltage) from the amp to speaker. It's a simple job. Copper, silver, aluminum, any decent conducting metal can do it, but they due it differently. (I'm referring to cables that do not have "networks" on them because that is a different discussion completely)

Electrical energy is NOT in the cable. It is stored in the magnetic field around the cable. This is ampere's law. As the voltage is reversed the electrons move in the opposite direction with the field reversing.

"...while energy flows fast"

Energy does NOT move or flow. Energy cannot move it is just a scalar number (joule). It just exists. Power is a measurement of energy / time, like a watt is a Joule/second. We never say the flow of power it is just 10 watts just like energy.

Power (in watts) = Joules/Second
= (Joules/Coulomb) x (Coulomb/Second)
= volts x amps
= number of Watts

Energy is never gain or lost it is always preserved. Energy is never directional. Thermo 101

Electricity is directional (we usually say + to - but that is a different discussion).

So electricity/ electrons/ current moves back and forth on a AC circuit, and energy does not. How can a cable be directional when the energy is not in the cable and it doesn't move, but the electrons that do move back and forth equally prefer the direction of the cable? How do they know they direction of the cable?

Jea48, the speed of propagation depends mostly on the medium. Since the electromagnetic wave is comprised of photons, it propagates at light speed in a vacuum but somewhat less in a metal conductor. All the other things you mention are pretty irrelevant. Does that answer your question.
