RE: "How electricity flows in an AC circuit"

The electrical *power* is contained in the electric and magnetic fields that extend outside of the conductor. But is the *power* the same thing as the *signal*? For audio the answer is almost certainly no. We know what produces the power. Power is a calculated quantity, based on current and/or voltage, and so is current a calculated quantity. Current is calculated from the moving charges, I.e., the free electrons. So, what's the signal?

Furthermore, electrical power is a scalar quantity and thus has no direction. Same with current.

Now, electric field and magnetic field ARE vector quantities, but their directions are perpendicular to the direction of the electron motion.
