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.
